I've sold quite few pieces through TMR and have been perfectly satisfied. One option they offer is consignment sale - it can be worthwhile if if you're in no hurry for your cash.
The Music Room
With all the talk about PayPal and the IRS, I'm considering other ways to sell my unused gear. I've been thinking about The Music Room. I have the system I want and have no need for trade ins. Has anyone else sold items to The Music Room? How was your experience? Did they give you a decent price for your gear (I understand they need to make a profit too). I just don't want any complications come tax season next year...
