I'm interested in hearing some opinions for the "best" general purpose machine. I've been running a 13 hp Honda gx390 and am looking to step up to a more professional machine with a higher gpm. The 13 hp gx390 home depot special just doesn't cut it. I don't have a huge amount of money to invest although I'll invest whatever it will take to get a reasonable professional unit, (even if I have to buy 2nd hand). I'm primarily doing residential homes and commercial retail outlets with an opportunity to expand to some surface cleaning. I appreciate all the advice that is unselfishly given by the professionals that post here. I've gathered a plethora of useful information. This site has helped me transcend from 'hack' to an aspiring professional. Thanks! Scotty
