fair complaint about Audiogon, violating no guidelines, removed

@OP, 
I concur, sellers remorse shouldn't be condoned. If you post a price, then you have to honor it once payment is made.
That being said, I would just move onward and let it go. Karma will provide balance to both sides- at least, I hope.
Check Hifi Shark for your piece of equipment. I bet you will find what you are looking for, and at the price you want eventually.
