What that pic should have read like:
16 foot rental trailer, $65
120 feet of rachet-straps, $30
9 classic arcade games from the 80s, $2700
Look on the dude's face when he realizes he could have built his own Mame cabinet (with help from BYOAC) for less than $800...priceless!
That has the smell of a bulk buy. The guy probably laid out $500 - $1000 for that trailer full of games. Very few collectors will buy multiple games at "full price" at the same time. Plus, that conversion game in there is a dead giveaway that he bought them all in one lot. If he was picking and choosing, he probably would not have chosen that one (collectors of 80s games largely HATE late 80s conversion games). I only buy conversion games if they are coming with something else, or if I am getting a bunch of them for cheap (bought a lot of 7 Final Fights, Street Fighter 2's, etc for $450 once, sold them all later).
Also, the multigame.com url leads me to believe that it is Clay Cowgill in that picture, and he CERTAINLY knows about Mame, and is one of the smartest arcade techs around, and thus is not going to be paying full price.
