If it was me, I'd choose from the factory outlet and get one of the following. (Note: I'm not a big fan of the M3). I've used the M22 for quite a while without a sub and was ok with that, but I wouldn't use the M2 without a sub.
M22 + wall mounts = $504 (Leaving $146 for sub)
M22 + stands = $620 (No sub)
M2 + wall mounts = $346 (Leaving $304 for sub)
M2 + stands = $462 (Leaving $188 for sub)
