As a first few months STLE buyer and also bought XMLE day one (mistake), I can tell you Stern is poop with code.
Bought: Tron, IM, AcDc, Met, TWD 2-3 years after release -- priceless.
With the exception of IM code (it's fine but could use a bit more something I won't say just what) and Tron (missing call outs for supper spinner, pops, etc.), the other codes are great (they could use a tad more ?).
My point is, Stern code is not to be trusted for me to buy before it's been out 1-3 years.
