hi all, i came across a silver sabre umax for sale and am thinking about buying it. i dont know anything about tesoro's. I am thinking about getting it as a backup, second machine or possibly a primary if i like it better. i have done a bit of research on them and am not sure if there is a difference between the silver umax and the silver sabre umax. it looks like a very simple machine to use and have read a few reviews, but i would like to hear from a few who use tesoro's everyday. any feedback would be much appreciated! thanks!
