It's the nature of the ham radio beast for as long as I can remember. At any ham fest you'll find people asking top dollar for the stuff they're selling, and then they nickel and dime the other vendors who are asking reasonable prices. It's not just big-ticket items either. I was at the Orlando hamfest last year, and a guy has the base to an average straight key....no level or spring, just the base....and the base was split in 2 pieces. I figured the fiber washers and spare hardware were worth a buck or two, so I asked how much, and he said $20. I literally laughed out loud....I didn't mean to, but it just came out. To which he responded, "Okay $10, you can glue it back together.". But, you have to remember supply and demand....highly sought rigs will always sell for close to what they were new. I bought an FT-1000MP last year for $900. When I bought one new in 1997 it was just north of $1000. Same with the ol' IC-706MkIIG. Even the guy with a coffee can full of old air variable caps, large crystals and tube sockets is going to ask a lot because you can't find them anywhere else. The 7300 is a highly sought rig, but time will tell if it holds it's value. For now, 10% might be enough to tempt someone.
