I am looking at one of these as well but have not been able to look at it in person as of yet. It looks like the base of the TMC 100 is slightly different than the ProLight 1000 and I was curious as to the material- cast iron or the polymer composite? Also, does it have THK style linear rails or dovetails or a combination of the two and if so, what axis is what? Sorry for all the questions!
Best,
Ryan
