I don't know if you're already considering this or not, but unless you're one of those guys who just CAN'T wait 3 to 4 weeks for your speakers to arrive, then look hard at going with speakers from the Factory Outlet (found on the main page). Those of us (I used them for all of my speakers) who have purchased through the F.O. have yet to find a flaw in the finish, and the drivers & everything else are perfect, they work and sound identical to the regular merchandise, so no worries. You will enjoy 10% savings off of the original price, plus if you're ordering 5 speakers you'll get another 5% off of your total order, so 15% off all together.
This might help you move up to the M22's, or at least the M3's if that's the way you want to go. Or buy the M2's, try them out for 30 days, and then if you don't think they'll work return them for M3's or M22's. You can also try out the different center channel speakers to see which you like the best.
