I hesitate to get involved in this, as there is no way to know the facts, but I can definitely see why Chief is suspicous of multiple identities, or at the very least collusion between these sellers on Gunbroker. The first picture in both auctions seem to be composed very similarly, and I would suspect on the same wooden desk or counter.
I certianly do not begrudge someone setting a high price on whatever it is they want to sell as long as the description and facts describing the item are accurate. It's the sellers right to ask however much they wish for an item, and it's the buyer's option whether or not to pay the price. Buyers should have the duty to educate themselves about the market before plunging into a substantial purchase, and if they don't, it's their mistake.
I, for one, have paid way to much for some firearms, just because I was impatient, and also really didn't do a good job of researching the market. One guy on HKpro hung me with a P7M13 that he described as "mint" that while in good shape, was not what I expected. To this day I cringe when I see the word "mint".
There will always be tension between buyers and sellers. We can only hope that both sides bargain in good faith. In this case, I think Chief has some valid concerns.
