I'm just getting my Bridgeport Boss 3 running and am looking for tool holders.

I have a DA200 and DA180 collet holders and after getting a couple collet sets for them, I'm finding the run-out to be inconsistent; for example 2 - 5 thou on a 1/4" DA200 collet. Either the holder is no good or the collets were too cheap (from ebay). I just bought a 1/2", 5/8" and 3/16" Erickson NMTB 30 rigid holders, but that's about all that's left there. I've read about the NMTB 30 grinding procedure (beyond my skills), just hoping these will fit since they are branded holders. I also did enough Googling to get my PC locked out of the service due to "suspicious" activity LoL!

Thanks.
