I stopped by my local dealer to check out the 4401. He told me that a customer just bought a 5100 a week ago and wants to sell it for something more powerful. Now based on the numbers the 4401 seems to be a better blower. How is the Strato better than the 2 cycle? Based on the new purchase prices why is the Strato $54 more with lower specs? Which would you get and why? 4401- $319 + 7%= $341 NEW 41.5cc, 2 cycle, 2.6 hp, 671 CFM, 183 MPH, 19.6 lbs 5100- $325 total(used one week) or New $369+7%=$395 50.cc, Strato, 2.3 hp, 664 CFM, 163 MPH, 20.3 lbs PS- I know, I should get the 7001 or 8001. That's not in my budget. I was lucky to convince my wife out of getting another craftsman handheld.
