This is a new full size arcade system from AtGames. I don't know much about AtGames and apparently they have a mixed reputation in this area but this particular product is getting rave reviews for build quality, value, and flexibility (ability to load games thru a USB thumb drive). I scored one from Sam's Club this past weekend and they are offering it for sale this coming Saturday at $450. The only other place to buy is from Walmart at $599. The Sam's Club special edition comes with a Blast dongle that includes Galaga + PacMan.
I have got to say I absolutely love the system so far. There will be plenty of critics I am sure but for someone is not handy enough to custom build a MAME cabinet, this one is great for the price.
For Sam's club: they currently show this as online only according to the website. But they are available in store as well - I picked one up in Woodbridge, VA and apparently they sell them as fast as they put them on the floor. If I have time, I plan to see if they will give me a price adjustment on Saturday to the sale price. But, at $499 (the price I paid), I am not complaining.
The real value is to load your own games. I am totally new to that process but there are several helpful Youtube videos on this front and I am happy to share those if interest.
This is the link to Sam's one day sale this coming Saturday.
