My thinking is that if you bought a part and then decide you don't need it, you're gonna take a hit. Like driving a new car off the lot. Instant depreciation. Some folks are in a bind and have to try and get what they can. I've seen lots of ads for used injectors asking more than I paid for mine new. I make an offer accordingly and they call me a low baller. I guess I'm a cheap bastard, lol. As in any free economy, it all boils down to supply and demand. Any widget is worth what you can get for it. Personally, if a private seller isn't offering a deep discount, I'll pay a little extra and go with a respected vendor just to not have to deal with the angst of the transaction. Later.
