I can go check out an ISA 430 but I wasn't sure if they are the same preamp or not (I just wouldn't have them use the channel strip stuff).
I can also go check out both the sm7b and the 4050 through the ISA430. I can't go check out a reactor unless I found one in a guitar center with an associate nice enough to let me try it. haha
I was also looking at the Black Lion Audio 1073 clone that is coming out soon as well as a WA12 preamp. It sucks but I'm pretty set at around $500 for the preamp.
