I think it would probably be fun to still go, but I wouldn't go expecting "Oh yeah, I'm going to take five hundred bucks and pick up ten cabinets!!!!!!1!!" kind of deals.
Oh I didn't expect that all...
Just looking at the fact the seller tried to get $5000 for a water damaged, non-functional, rusty Warrior game with no wiring harness tells me a lot though.. not to mention "restored" Galaxian 60 in 1 machines for $1600
Its his business to price his property as he chooses just as its my business not to attend. Failure to even give people a general idea for what some of the items... There will be no deals for buyers which is odd for a guy claiming that everything must go toot-sweet.
Again I have run into this type in the car trades, I know the type well. I would not be the least bit surprised if those machines are still sitting in a warehouse long after the "must go date" or in a landfill out of spite.
