You can build one for a fraction of the cost if you have the skills. I had one and it satisfied the itch until I could find a real machine. I would still have it up but ran out of room when I added more real pins. Now that I have more room I want to get it back out, but gave up the computer to my son for gaming. They are fun if done right with force feedback and all. Still any real pin is better.

I will also add that where I live real pins are much harder to find so it was about the only thing available at the time.

One thing for sure, if not setup correctly or due to the tv / monitor used and any delay in flipper action makes it unbearable.

I have 14, but spent less on the entire collection than some do on just 1 machine. I buy broken and fix, then restore. I like knowing every bolt and screw on my machines for when a problem comes up. I can't play a game unless it has 0 issues for some reason.
