I have the cheap stuff. Running a 27cc Cub Cadet Powerhead. I have the string trimmer,brush saw, hedge trimmers, pole saw, tiller, and edger. I have run many tanks of gas through the powerhead since the first week of August with NO problems of any kind. I plan to buy another powerhead this spring so that I have two in case one has problems or I need to run two attachments on the same job therefore I won't be constantly switching tools. It is frowned on by those that run Stihl, and Echo products but it is making money for me and until it gets to be a problem I intend to keep running it.
