How big is your property? How many leaves? And what is your absolute max budget?
I bought a BG55 brand new a few years back 2013? It needed to go back and get a carb a few days after I bought it. I can be finicky to warm up at times, but once warm it runs great. Very handy, compact unit. Use it all the time, grass clean up, washing cars, removing snow, cleaning roof/gutters, drying large parts. With that said, it doesn't have the power a backpack does and if you have a lot of property or trees that produce large leaves it would be pretty tiresome.
Looking back I might have gone with the BG85 or 86, the next step up. I got the 55 for ~$160 I want to say out the door with a "pack" of the still oil for warranty. The 85 was right over $200 IIRC.
