Ars Technica has an informative review (http://arstechnica.com/news/posts/1086241264.html) of 10 different USB 2.0 Hi-speed flash memory drives. The Transcend JetFlash2A - 128MB (US$38) and the SimpleTech Bonzai Xpress - 256MB (US$80) were the overall winner of the test (with the Transcend the only bootable one!).

I love those tiny sticks and the fact that you can run entire operation systems (preferably Linux) on them.

Interesting review! Amazon has a special $32 after $15 Mail-In-Rebate deal for a SanDisk 256 MB Cruzer Mini USB 2.0 Flash Drive:

So you get twice as much memory for the same price ;)
