The best machine IMHO is the one that works for you. But mostly the SERVICE from the dealer is what I look for. After having 2 TOL machines and having NO customer service after I purchased the machines. I learned that lesson. I too have the 830 and think it is great.....just what I wanted, but mostly I am happy with the continued fantastic service I receive from my dealer. Nothing, no nothing will be right IF you don't have the support from the dealer.
