Check out the SoundStream D'Artigan.
Thats what I use. I am very happy with it. Someone else refferred it to me. I started thread in this forum a little while back asking for amp recomendations and thats what someone recommended.
It has 6 channels and is 800w RMS:
65w x 5 @ 4ohms + 400w x 1 @ 2 ohms or
100w x 5 @ 2ohms + 500w x 1 @ 1 ohms
I think the above is correct but do a search to make sure.
Also it has an option (if 400w isn't enough for your sub) to double it by bridging with an equel amp... so you have expandability.
Don't know any others becasue i havn't had experince wiuth others.
I hope other people chime in with their experience
