The price of a system is only set when its actually sold.
This machine here is a fully loaded one. For an amiga enthousiast loaded with cash this might be an interesting buy. At least when that person is not after tinkering with hardware or likes to collect items himself.
Then this machine is worth quite some cash considering it is an A4000 with an 68060. So people wanting a beefy amiga will bid higher on a system like this. It saves them the time of gathering material to acheive the same.
Personally I like to gather items myself. I started with a stock machine looking for upgrades and expanding it along the way. In the end you probably pay more in total but I think it is more fun building an amiga that way.
An other type of buyer might show interest in this kind of machine. They buy the loaded system and dissassemble it selling the parts to buyers like myself.
This way they try to make money out of the old amiga.
I think $800 is too much to attract that kind of buyer.
