I run an 820 and a 620 in my 38, both at full throttle, with a deep sand bed. I also have a 300gph HOB filter helping stir things up. Granted, my tank is heavily SPS, but I haven't had any problems at all. You can get away with a whole lot more flow with these powerheads versus standard jets.
In a 90, I'd be thinking about a pair of 1100s, at least, with the understanding that you have a return mixing into the equation.
I hope it's not out of line, but I highly recommend OceansAquariums (run by Noel), phone (559) 304-5674. I just bought an M820 for far less than anywhere else I've ever seen.
