look at TCP global. They have lots of guns. Countilaw said he uses the Finishline, I think, and said he loves it. I haven't used the lvh 400, but I know the Iwata I DID use was an EXTREMELY slow gun. If you like the speed of a SATA, it is REAL hard to get used to going slow. And the older Iwatas had a very narrow pattern so not only were you going slow, but you were having to go over the same panel COUNTLESS times.
BUT, me personally, I like to paint fast that's why I loved satas.
