I've only purchased and sold a couple guns online, but the feeling I got on one occasion was that the gun I purchased, which awas really on the very low end of the value-spectrum, didn't get the full attention of the seller (who in this case was a more experienced "collector" who had a stable full of expensive guns), and consequently he didn't feel the need to go into excruciating detail about the POS clunker he was unloading for a song. It might have been a stretch for me, but it was chump-change just to make room for him--and consequently I got terse, single-syllable answers to only some of my questions. I don't think he was dishonest or intentionally unresponsive, just thinking "this gun is priced way below what it could be worth, why are you bothering me with all these silly questions--just buy the damn gun, you'll be happy with it." In the end I took the chance and was happy, but it really was hard to stomach at the time--a couple hundred dollars may not be a lot of money for some, but it's still a mortgage payment, a months worth of food, etc. I still don't understand why he couldn't or wouldn't put in the effort to describe the gun with enough detail to be useful either in the original description or the answers to my questions (and he DID know better).
