Yeah, i got all my current cabs from quarterarcade. Anthony is really helpful.
It depends how you define cheap / expensive. I got Track and Field, R-type, Tapper and Arkanoid in a nice green Taito cab from them, shipped to Europe. Packaging was excellent, quality of machines is very good, especially tapper and Track and Field and was a whole lot more cost effective than what I could have sourced locally for the same money.
Highly recommended!
