I got mine out of Pinball Centre in Germany and was initially dissapointed as the quality of the decal as it seemed really thin compared to what retro arcade refurbs put out BUT really happy with the end result. I chose the Pinball Centre ones as the pics looked to be a bit better.. the artwork looked slightly more detailed. I could be completely wrong but that was my impression
The quality is actually quite good just need to make sure the surface prep is 100% blemish free otherwise it will show up any flaws. Also noticed Retro Refurbs are thicker which I like but the cost for that is some stretch so the seem to shrink by a few mm in the months after applying. Again this may be because of the way I apply the decals but the Pinball Centre decals did not shrink and look great.
