If this guy has a pair of perfect 360 conversion kits for cheap then where is he located at? I'll RACE YOU OVER THERE !!

. Even if you find that you don't like them (can't imagine why) you could just sell your converted sticks on Ebay and probably turn a nice profit

Then go out and buy yourself some new sticks (some mechanical rotarys and an interface from Druin maybe?

) Ofcoarse you'll have to kick in a few of your own bucks for that setup but what I'm saying is never turn down a good deal. If you don't like them, their is always somebody who will so you shouldn't have any problem unloading them.
Just putting in my 2 cents.
