I personally think both are amazing and I applaud both sellers for making them. I went with the cheaper route because I actually like the look better. ( seems more like real stone )
I say charge what you want and let the market decide, I'll most certainly be buying some of Matt's other mods and I just got a package from Mezel mods. I like to support all of the pinball community that spends the time and effort to make such great products!
