I wouldn't mind getting my hands on some INFI, but 400 bucks for that blade is knee-slappingly hilarious.
I noticed they are still available on the store - I imagine it'll be a while before these guys sell out <img src="/ubbthreads/images/graemlins/rolleyes.gif" alt="" />
At this point, I think I'd be perfectly happy with a SR-101 S5, thank ya very much. If INFI is available, and I manage to snag one, that's cool too, but I won't cry if I have to "settle" for the less expensive CG.
