WTB: Best price for a new 250 or 320 GB drive in the US?

[snoutmeat]

Yee-haw! I've been using my Phatbox in my VW in the USA for several years now and have loved it (but wished my 20 GB cartridge were bigger). When I bought the unit, the hack did not yet exist. I just decided to research whether or not a workaround had been found, and was excited to see that I can hack my Phatbox now to use a bigger drive!

I have the USB 2.0 dock, so it looks like I'm not stuck with the 127 GB limit. Honestly, I think 100 or 120 GB would be big enough for my purposes, but it appears that a 100 GB or 120 GB drive is almost as expensive as a 250 GB drive.

Websites like pricewatch aren't very helpful because they show all 2.5 inch notebook drives and don't differentiate between IDE and SATA.
After much website browsing, I have found:

Does anyone know of better deals on 100-320 GB drives? I could get a 100 or 120 GB if one were for sale somewhere for something like $30-40 (same price per GB as the bigger drives). Everyone seems to want to sell their 100 and 120 GB drives for $60 or more...

Any reason to pick Samsung over WD or vice versa?

Thanks!
