APR have been using Tim and Stu's playfield restoration service with fantastic results. All my customers that have asked for playfield restoration, or, for a clearcoat "upgrade" have been pleasantly surprised with the price and impressed with the quality of the end product. APR has sent several playfields and we have another 6-7 for the next batch.
It is always a good idea to ask for a quote, rather than speculate on pricing that is "out of reach" for most collectors. The reality is that it is affordable, and the finish is second to none.
