I own several BP blowers, including two top tier models- a Husky 570 BTS and BR 600 Stihl. Like I said in my earlier post, the Husky 350 they sell at Lowe's is plenty for your needs as a homeowner and is in your price range. Is bigger better? Almost always. That is, unless you simply can't afford it, and/or you want to stay married.
The 350 will do fine for your place, especially if you aren't the lazy type of homeowner who tries to wait and do the leaves all at one time, on one day. Do them once a week throughout the fall with the 350, and you'll have no problems at all. I would go to a local Husqvarna dealer though if you have one around your area, since you'll get the same machine at the same price, and better service if needed afterwards.
