and purchased a used GraverMax on Ebay today. It came from a retired jewlery makers shop, or so I am told. It came with the GraverMax, two handtools, and a rotary tool (a GRS 850 I think it was) and a pressure regulator w/filter. The seller said he didn't know if it ran but observed family members unhook it from the compressor and they said all was in working order. I bid on it even though there was not evidence it would work. I am learning on a set-up just like it tools and all. I will let you know if it turns out to be a bust. I called GRS and they told me that they could help get it going again if it did not run properly. Wish me luck.....:clapping:
