Looking for good External Hard Drive for Airport Express Base Station-USB Hub

I have one of the new Airport Express Base Station's on the way and will be using a Hard Drive on it as a server for my home network. I"m interested in suggestions. Since this is bieng used on a large desk I don't need anything compact but definitely want a reliable drive and I"m looking at sizes of 540Gigs to 1TB.
I have looked at the Lacie's Little Big Disk as well as Western Digital's My Book Pro series and some of maxtor's offerings such as the One Touch III. I didn't see anything impressive from Seagate. Any other companies I should look at? I obviously need USB 2.0 but as well I'd like Firewire 400 and if possible Firewire 800 so I can use these when I need to hook into the computer locally for faster speeds. I think Ethernet would be nice for future proofing as a network drive but as well as long as Apple has this disk feature in the Base Stations it's probably not a necessity to me. Or am I better off just going with a good Gigabit ethernet drive and not using this USB 2.0 feature?
As well, since I'm going to be hooking up a printer to this as well I'm looking for a good USB 2.0 hub.

The USB on the Airport Express only supports a USB printer, not a hard drive.

The Extreme on the other hand does support a USB hard drive.

I'd look over at http://www.newegg.com. They have great prices.

I meant to say Extreme, that definitely makes a difference.
I thought of another question. If I get a drive that has firewire 800 and/or 400 in addition to USB 2.0 can I use the USB 2.0 on the Extreme Base Station across the network and as well for a local desktop computer (I plan to get a Mac Pro within a year) can I hook the firewire directly into that.
In otherwords use it as a netword drive across the computer but yet with the mac pro use it directly as a system drive?

I honestly don't know 100%, but I feel strongly that one port will out-weight the other. That is, either the Mac Pro will get the drive or the Extreme will get the drive, not both.
