Quoted from vid1900:JJP and Wayno wanted all the money up front.
PPS only wants $1000 down and the balance 1 week before it ships.
Skit-B, Heighway Pinball, Quetzal were only asking for a deposit too. But how many Predator, Full Throttle and Nemo pins (besides prototypes) have you seen? Expect delays - at least compared to what the creators believed. A single missing/late component from one of the subcontractor and you're late.
