The only thing I can think of that I would pay for is ColorDMD and a Shaker Motor (not the cheap shitty ones). I do like I Aurich's stuff so I am going to be focused on pins with his stuff over one without. Everything else is a toss up, it may be hassle to be removed or a little bonus if I like it.
Pin Stadiums are a hard no for me, I do like that style of lighting on certain pins but no way in hell am I paying that price for a mod I can do myself just the way I want it for a small percentage of the price.
