Finally got some flat work jobs and now i need to make the leap and spend some dough on a surface cleaner. Looking for a hover style,20 inch or so. I've done searches etc. Can anyone help point me in the right direction as Ive shopped on the web but have found prices vary greatly for the same models. Need to find the best deal. I kinda like the rotoblaster (as far as what ive read about it) but im open....
