I received the new impeller from MOPS.  Put it in the MAG 7 and I get the same vibration noise.... Hummm...  It is less noisy than the previous RIO but nevertheless I can't stand it...
So OK, just for fun (ya got a few $ to burn) I am going to order a OR 2700 from the US and see if it is more silent than the MAG. 
Cost: (49.99 US + 15.00 US  shipping) x 1.65 + 7% TPS + 7.5 PST + Customs fees =
