Many prices listed by Sellers on Gon are absurdly high, for used stuff - especially cartridges or tubes "with only 200 hours" on them - with no warranty or realistic return option, and considerable legal risk. You see the same things which haven't sold listed repeatedly with only trivial reductions in the asking price. This is a tiny market, the offerer may suspect that there may be few if any potential buyers for old, obscure gear, and it is not uncommon to get no offers at all. A buyer has almost no legal recourse (sue in another state? get real) on a bad deal, and the aomunts involved are too low to justify suit in any event. The risk to the seller, who doesn't ship until payment is received, is relatively small, but the risk to the buyer is rarely factored into the equation in a reasonable way. So if someone responds to a price that's too high with an offer that's too low, that is not unreasonable. People can offer whatever they want, it's still a free country! You never know, the Seller may be more interested in unloading something he doesn't use and moving on, than messing around trying to squeeze a few more bucks out of the deal. A seller can ignore the offer and let it die on the vine, or make a counter-offer. Give the stuff away if you can't get what you think it's worth. Whining about "lowballers" is pathetic. It's just spam, delete it. Besides, deals are governed by the "Golden Rule" - the one with the gold makes the rules, not the silly seller.
