Honestly: I lost a large chunk of interest when I heard you'll be charging around market value for each machine. You must have overpaid. I'm not understanding the hype and excitement as much as others anymore due to this - if you want a few hundred games at market price go to Pinfest. Usually what makes these bulk buys special is the lower prices on these project/very dormant games which get people excited.
Now all that is left is the fact that they're popping up for sale at all, good for games that don't come up much, but I think everything besides rarities/low produced games are pretty findable these days if you really want it and have an ounce of patience.
It's like a well-priced estate sale vs. a new Walmart opening in town. This is the Walmart. Same stuff others have, at the same price everybody else charges. Might be cool to take a walk through the new construction and just looking, next week or next month or whenever you find some boring spare time, but not worth waking up early and lining up at the door on opening day for, especially if nothing is "on sale". Sooooo... why exactly are we all standing around? Just go to the Pinside Market/CL/eBay and see if the title you are looking for is there.
To be fair, perhaps you just wanted to be the Walmart all along and sell slooooow and it is PINSIDE that got the wrong idea and figured this to be yet another usual bulk fire sale - that is likely the rift that caused this thread to be so long.
On another note, people are saying they would buy (and replying on an internet forum with a sentence seems to be easier for a LOT of people than actually committing to a purchase) but I am worried for you that you will have major trouble selling these like this. You hop back and forth between "These NEED to go" and "I can wait a lifetime for my price!"... which is it, truly? You are not going to have a "fire sale" unless the prices are even better than low - else everything will definitely sit around longer as people around here have the same collector "not a crazy deal? I need time to think about this, it's low priority" attitude, especially at retail prices, regardless if you have that time or not. If people worry somebody else is going to get them/want to get them first it really gets things moving.
Looking forward to your Pinfest selection!
