take it from me, the resident expert, you can't go wrong with the M3ti and any sub recommended by pmbuko.
(hhmmm, on second thought, nobody'll get the sarcasm so don't listen to me)
seriously though, i've received great advice/tips here, so listen to these guys. and my new speakers just arrived today so i'll let you know how i like 'em. and i also enjoy a good trance buzz, i'll run a little Ruff Diverz Pres. through 'em - the "dreaming - percussion mix" should be a nice test.
