Hi guys! Long story short; I have a basically brand new Sigma 2x teleconverter for Nikon that I bought on the cheap a little bit ago; hoping to trade it for a Canon mount. At this point, though, money is kinda tight, and I think I'd rather just sell it. I posted it here on the marketplace, and have it listed on Craigslist with no bites. I'd rather not spend another $25 of a FM membership (my last one expired, and I don't want to spend the $$$ for one transaction), and eBay fees are a pain. Any other forums worth looking at? Any other outlets? These sell for about $300.... I'd be happy to get around $200. So, I'm not being greedy. Whatchya guys think?
