I got the normal XLR8 in my rig (not sure if it's the older edition or not) from Frys. I didn't really benchmark the speeds, but it's been working just fine for probably well over 6-7 months now. I'm fine with it.
Tbh nowdays I'd probably hold out for an Evo though, they're prolly much faster in most ways. You can get one right now for like 33 bucks more.
I have the non pro version of the PNY. Compared to my OCZ vertex 2, it hangs in very large folders and is slow. if not for the storage size and my desperate need for space, I'd have returned it...
