It doesn't take alot to be polite. OBO is just that. Your offer may not be his best, but if you're a serious buyer, if he wasn't willing to accept an offer then he should have put firm or courteously declined and counter offered. Many times I've bought and sold equipment right here for +/- 20% off OBO and in the end both of us were happy to have been able to put together a deal. This guy is just too proud, too stupid, or just a putz!!!
