Anyone have any experience with the Acomdata brand, and specifically the Acomdata 250GB HD250U2E3-72? It's an external drive, and after rebate, Fry's online store is selling it for $150. I'd prefer going with a brand I am more familiar with, though I'm only going to be using it to store various ISO's. I do work my drives pretty hard though, a lot of unzipping and deleting. But I'm on a budget, and that price is looking mighty tempting. Any personal anecdotes or advice would be much appreciated.
