I would go with a 60 in 1, hands down
its a great, great, great board and will last a long, long, long time
I sell them in cabinets to people and they love, love, love it
I love it because it just works, works, works and never get a call back from the customers because of the game board, ever.
the 412 in 1's are slightly, slightly blurry. They can fail at any moment for a number of reasons
I can see it and it bothers me to no end although I do love Tutankham and Bagman and Super Bagman but the rest of the games I could do without. I keep a 412 around just to satisfy my taste of those three games but I don't have confidence in selling a multicade to someone with one of those in it. I just think the phone is going to ring at any time with some complaint/failure.
Run, run, run far away from the computer based systems is my advice.
Never bought an arcadeSD. Probably will never only because the 60 satisfies my almost every need.
Always have a 19 in 1 around even if I only sell 1 or 2 a year. Have to have some Robotron and Defender around at a moments notice.
cast in order of appearance:
60 in 1
19 in 1
412 in 1
and that makes me a happy gamer
your mileage may differ
I saw a 60 in 1 on ebay for 36 bucks. you will get decades of happy gaming out of it if you put a new 21 dollar switcher on it.
good luck
