Now that you're here you have some reading to do. Search for RF-45, tons of threads on builds.
There are no plans for RF-45's, everyone (brand) is different enough to make universal conversion schemes not work. The MTW's are nice with the larger travels, if I could have fit them in my corner I would have. But I'm squeezing in my PM-45 with 9" of Y as oppossed to the 12" of the WTW MD001.
If you want turnkey I'd go Tormach. If you do a full bells and whistle conversion with servos, a nice stand, belt drive, enclosure and flood coolant you will be within a couple thousand dollars of what a Tormach costs and 100's of hours in labor.
Things to think about.
