I own two Woz RR (late build meaning 2017) and DILE (built in 2018).
Both were bought by me but were low play examples and I've had no trouble with either one.
I would recommend Woz (late build) and DI
both are super fun and site of the art as far as some of the toys and code (DI still more to come).
I've heard some bad things regarding early build games like 2015 (and such) needing light boards etc.
