I also agree the Edirol M-10DX mixer is the best mixer I have used....and I have used a lot of mixers including the same Alesis Gary uses...I also used the Mackie CFX12...both the Alesis and Mackie served me well...but the Edirol surpassed both for me..Te RAC alone made the change worth while..
I think you can still find the M-10DX for around $250...The deals for under $150 were the bargain of our time..
Look in the future..the Edirol label will be replaced by Roland's Cakewalk division..It already has...
Forgot to mention..the vast number of mixer users...do not use them properly...just about every stage set up I see...do it wrong..then complain abour noise and feedback...
