Welcome to thinkpads.com! (ooh... long time lurking, huh?

)
Several points after scanning their web site:
- The "legacy" systems (essentially, the numbered series systems; 240, 570, 770, etc.) appear under the IBM brand (Other Thinkpad); the remaining systems are with Lenovo
- Not all systems are listed; Lenovo/Thinkpad is missing T21, T22, SL500 from a quick look
- They seem to correctly recommend the proper modules for the "problematic" systems; PC100 for T20 and PC133 for T23 (no mention is made of "low density" for the T20 however)
- No mention is made (as far as I can tell) as to the source of their modules; whether they build their own or simply buy them from some other company to be re-sold
- Links to the site's FAQ appear to be dead; in fact many of the links I clicked on the Site Map page simply returned me to the main page
- Listed on the Site Map page, under the Support heading, is a link named "Contact 4 All Memory". This goes to
http://www.4allmemory.com/ , which appears to be owned/operated by the same company. While the 1-800 numbers are different, the local (toll) numbers are only one apart (314-856-4001 and 314-856-4002) and the FAX number is identical
- The prices are a little bit high (IMO) when compared to what you can get off of eBay but I guess that you are paying for the "guarantee" that they work for your system
edit: After re-reading your post, I realize you are more interested in the hard drive aspect of their business

. Any ATA, PATA (parallel ATA), IDE or EIDE drive that is of a notebook/laptop size (2.5" platters) and is 9.5mm (or less) in height, can fit and work inside the G41. The WD 320GB drive you referenced (WD3200BEVE) is $98.88 at memorygiant.com. The identical drive from newegg.com is $89.99. You'd have to click through both sites to see what the shipping/taxes are and then compare those final prices.
And here's some feedback about 4allmemory.com and MemoryGiant:
