Trying to decide between the Stihl 350, 430, 500, 550, 600. This is only for home use and maintaining rental property... not heavy commercial use. I want something that will move thick wet leaves, which my current handheld fails at miserably. The 200 backpack seems like nothing more than a hand held blower mounted on your back, so I did not even include that in the list. I am leaning towards the 430... but am trying to figure out if it is worth only a few more bucks for the 550 (which seems to be cheaper than the 500 for some reason?) I don't think it is worth it to go to the 600... overkill for my uses. I would appreciate anyone's feedback who has experience with these units. Thanks.
