raytech is about 3 months behind as rick i guess is working allown. i have 4 machines with students on three. it is a good well-rounded machine and long lasting. if you want the best thats the ultra tec V5. the ray takes getting used to but once you get the actions understood you can cut a stone very fast with it and you have the advantage of picking the cutting hand piece up and having a really good look at the work piece. the raytec and ultra tec are the only two machines i will recommend.
