Hello all, new member here.

I'm looking at 2 prolight mills on ebay. one is a plm-1000 with the r8 spindle, and one is a super prolight 1000 that may have an iso20 spindle (still waiting to hear back from the seller)
if i get the normal plm-1000 i plan to set it up with Tormach tooling system, and i just wanted to hear some general opinions on TTS VS ISO20 and which one i should go with.

Thanks!
