You could go:
-M60s without a sub
-M50s without a sub
-M3s and VP150 without a sub
-M22s and VP150 without a sub
-M22s and a EP175
-M22s and another manufacturers' sub
-M22s, a cheap sub and a VP100

By the time the bass geeks (I kid, I kid 'cause I love!) around here get done with you you'll end up with an EP600 and an eviction notice, though.

JohnK and others should be able to find you a good price on a receiver... that's really not my bag.
