FTP vs IE or Firefox Downloads

I'm trying to download a small number of zips of NED data from the USGS seamless server, here: "http://extract.cr.usgs.gov"
My problem is that my internet connection, a souped up 802.11b looking at a tower 8 mi away, is marginal at best. I've found my FTP client to be far more robust and faster the either IE or Firefox. I just today FTPed into the NHD site instead of using IE and all the zips were in the root directory. Just had to select my group and copy paste and wait for the download.
So I'm hoping I can use use the same procedure for the USGS seamless server. I tried ftp://extract.cr.usgs.gov and I couldn't connect. Anyone know the FTP address?
Thanks

Roger,
Would you be interested in purchasing the TIGER and NED data? I am thinking about offering it on the website? It would be $99 for both 2006 Tiger Data and $99 for U.S. NED data.
What are your thoughts? -
I don't believe that there exists a public FTP site for directly pulling down that data. I think that the seamless.usgs.gov site dynamically extracts the required data into files for download. I'm not sure what the format of the source data is, it may even be in a database of some kind.
Thanks,
Mike

Do you know how to FTP to "http://extract.cr.usgs.gov" ? -

Since its a xxxxx.zip file, just like the NHD xxxxx.zip file I was hoping. Those files have to exist on a server some where. If I could FTP to it, life would be sweet.
Is their a download client for either IE or Firefox which offers more robustness? I'll get half way through a 160MB download and it'll just die, not a clue why. On a good day I can D/L at 2MB/min, often 1/4 that.
My FTP client seems to get through the disconnects and reconnects and picks up where it left off. IE and Firefox just die.

Roger,
You know, my mistake on the NED data. $99 is not correct. The next closest price on the net is $500. I would offer a 60 day introductory rate of $199 for it and $299 after that. It would be shipped to you on 2 DVDs.
Let me know if you are still interested. -

What is on the 2 DVD's ???? -
There would be the entire United States NED data on the 2 DVDs.

What resolution, what format? -
lol.
Yes, I have sold online before. I apologize that you are having to ask the questions instead of me presenting the product information and allowing you to decide for yourself. I have actually been thinking of adding this as a product available on globalmapperforum.com And when I saw this come up on the forum, I kind of just piped in without having all my ducks in a row.
Here is some more information about the data:- Coverage: Entire United States
- Source Data: USGS DEM data
- Projection: Geographic, NAD 83,GRS 80, decimal degrees
- Resolution: one arc-second (approximately 30 meters) for the conterminous United States, Hawaii, and Puerto Rico and a resolution of two arc-seconds for Alaska.
- Format GMG - Global Mapper Grid

Since I started this thread specifically mentioning 1/3" NED downloads, I assumed you might be offering 1/3's. I have no use for 1" NEDs.
Perhaps as your selling plans mature you could offer 1/3's too. All the other specs look good, particularly GMG.
If you recall, I started this thread looking for a download solution, specifically FTP. Didn't happen, but I have found a IE download client which works well: Download Accelerator Plus. A bit garish and rude with its ads but I'm able to download 1 x 0.5 deg 1/3" NEDs which are about 160MB, 1+ hour each. -
May I suggest you also try Firefox (Firefox web browser | Faster, more secure, & customizable) and the DownThemAll-plugin (https://addons.mozilla.org/en-US/firefox/addon/201) - works like a charm for all file types and with a lot of options.

Haven't tried the plugins, to many to know which. The good news, DAP is working well even if it's a bit rude. I've seen the speed drop to zero on a number of occasions and DAP picks up where it left off and I don't loose any data. Therefore little incentive to do more hunting for a prettier interface.
Thanks -
It is very strange that firefox crashed.
You do NOT need to install alot of plugins, only the one mentioned: DownThemAll - https://addons.mozilla.org/en-US/firefox/addon/201.
But until you want to try something new, keep up with IE and DAP. -
It is very strange that firefox crashed.
OTOH, DAP seems to just truck along. Making me overlook its ads and rudeness for that which I most care about, it works. No doubt their are other plugins which work as well, I'm just not compelled to look. -
Have you tried
USDA:NRCS:Geospatial Data Gateway:home
Looks like you can select 10-m or 30-m NED data and then they will email you link to download via FTP. NO charge.
