I adore my machine so can't say there is anything i wish i new prior to buying it except don't buy when it the lastest model because it will go down significantly in price so i wished i would have waited a year but love the features, reliability, ease of use. Have never regretted my decision. I do think if you spend over 1000 like i did you can't be scared to use it ootherwise the moneys a waste. I see too many buy them and never use them because of fear of messing them up but high end machines should work for long time with no issues. I feel for those who get lemons that need work straight out of the box. But i also feel if your gonna buy a machine in the thousand its cruicial to have a dealer that stands by their machines.
