Well I finally did it. I wanted to upgrade my M2's to the M22's. Instead of sending them back (the return shipping is brutal), I put up my M2's on a local want-ad site. I put them up and got a respose within 3 hours. The next day they were sold for $235. HAHA I just saved big time what a great resale value, although I was sad to see them go. So right online I went and my new M22's are arriving tomorrow.
