I don't know too much about other brands, but I have two 8G SanDisk Cruzers. One is only a few months old, and the other I've probably had a year to a year and a half. Both do a very adequate job, no worries, no problems.

I think you can walk into your local Walmart and get them for the same price you mention. Their website says it supports both PC and Mac. Check the sandisk.com site for more info on what is available and what it can do.
