I have an option of the BR600(stihl) or EB8510(shindaiwa) or EB620(also shindaiwa). they are all practicly brand new. i live in nj, so we get leaves, and alot of them, and i want it to be comfortable aswell though, meaning it is light and not much vibration. but i neeeeed the power. so please tell me what you think because i know all of you are bigger and have more experience then i do.
