I'm gonna pick one of these up in the next few weeks. Fall cleanup use and for use at my home. How much difference in power between the 9hp and the 14hp? I can count (5hp!). But, I have no idea if the bigger engine is worth the extra $$. Everything I did last year.....I did with a BP blower. I'm guessing the 9hp would blow away most BP's (no pun intended)? Almost $100/1HP diff..
