I hear quite a bit about everybodys top of the line commercial equipment, any thoughts on using top of the line residential for commercial? I am slowly trying to upgrade my equipment, but have had good results and pleased customers with my residential equipment so far for a quarter of the cost. Such as my Ariens Zoom which seems to compete well with the big boys. I started on a shoestring budget and seem to have been successful so far with my "cheap" equipment. Any thoughts? Did anyone else start "cheap"?
