This forum is in the business of selling audio gear for a commission. Perhaps not surprisingly, they take a very dim view of folks trying to sell their gear to one another in forum threads. They also do their best to prevent folks from exchanging their contact info in PMs.
Like I said earlier, if you're not ready to consign your gear to a shop or list it for sale on here quite yet, your best bet in order to gauge local interest is to post a list of your gear on craigslist. It's always best to sell locally whenever possible: no shipping / payment hassles and you get to meet nice people too.
