Hi guys I am at a crossroad and I would like your input on which way to go. I currently own a Seig 7x12 lathe and a an X2 mill, I have had them for a couple of years now and have stocked up on tooling and complimentery items. I feel I have out grown the limitations of the X2 and I am ready to move up to either the X3 or a RF 45 clone from either Lathemaster or Grizzly. I will be keeping my new machine manual with the addition of DRO. I have heard that the fit and finish of The X3 is superior to that of the X2, that is a big plus in my book. I would like to hear from guys that have the RF45 clone to comment on it's quality and fit and finish and if they can compare it to the X3. I make one off parts out of aluminum and steel (not hardened or super tough steel mainly mild). The X2 worked good with aluminum but the steel gave it more of a hard time, that's why I want a bigger stouter mill mainly. does the X3 handle mild steel with ease or would I be better off going one step higher to the RF45 clone? I appreciate any comments or if there is anything I have missed.
