hi. I have a br600 magnum, but I'm looking for just a bit more power. not sure of the difference between the 8500 or 7500. I'd be using the blower mainly for cleanups, and use the stihl for grass, driveways, etc because it's light and comfortable. have any of you guys used the 8500 or 7500? just wondering which one to buy, or maybe even the tanaka 7800 blower? I've seen good reviews for it...
