hey, i'm looking for good external hard drives around 250 GB of space. most of the external hard drives with that price is around 50% more than a hard drive that you can buy for a pc. i don't care about style, or brand, or build your own, I just want the cheapest external hard drive solution that is 250 GB, and can be capatible with a pc and my ibook g4. any suggestions? is buy-your-own-hard-drive and a seperate-external-hard-drive case cheaper than those one hard drive solutions? i was considering Lacie, but i find the price to be higher than other comparable solutions. it's a good product, but i'm tight on cash right now.
