Quality of cams --- Summit?

Yeah, I've never had a problem with the MP cams. I have a crane in a motor now. I was thinking on a Summit cam (mild) for a different project but didn't know if they were a re-grind, or new. 117 bucks is tempting vs. 200+. Also didn't know if the Summit was a cam that would run a long time. If the factory units could roll 200k like nothing, I don't want one that needs to be replaced in 30k. I'm looking at the Summit cam kit that's close to the 340 cam for a 318. It's 80 bucks cheaper than the Comp.
