Craigslist can be such a crapshoot really. This past spring I had a Pioneer SX-880 in near mint condition listed for $350, but was willing to let it go for somewhat less. I had a guy show up to look at it, and then proceed to tell me he was looking for something a bit smaller after picking it up to see how heavy it was. In almost the same breath, he said he was also considering a SX-1250 he saw listed elsewhere.
He also claimed he was running late on meeting someone for a dinner date, but rambled on and on about a variety of topics while randomly cranking the volume up to ear-bleeding levels to see what the receiver "was capable of". He finally left, and said he'd let me know the next day what he decided. I told my wife that I'd never hear a thing from him, and I was correct.
