I just bought a SanDisk 2 Gig unit for $59.00 at of all places Home Depot. Check it out here http://www.sandisk.com/Products/Item(1904)-SDCZ7-2048-Cruzer_Titanium_2GB__New.aspx
It comes with some preloaded software but it's easy to get rid of so you have the full two Gig.
For a first time user who knows little about this; what's the best brand of a 1GB flashdrive to use to backup data on a notebook computer? The data I'll be backing up is Quicken; not much data right now. I prefer something not too expensive but at the same time something that will last and not break tomorrow.
