I'm in need of a replacement for my blower/vac...may it's little piston rest in ....pieces.....I really haven't looked at these in years but since this one recently expired now I'm looking. I've got several properties with walkouts, window wells and such that require a vac/blower combo. My trimmers and such are Sthil...I like their design, safety features and reliability. The only thing I don't like about them is the dealer I have gone through.....most unhappy son-of-a-whitch I have EVER met!! So what have you used... pros and cons. Comments and questions welcomed. Thank you for any input.
