Do you need all that range? I'd urge you to reconsider. Once you discover its shortcomings as a superzoom, you'll feel the need for a constant large aperture lens. For your budget, the Tamron 17-50 f/2.8 is easily within range. On a 1000D body, this range is the most commonly found walkabout range, for wide angle work at 17mm, and some portraiture or closeups at 50mm.
