I looked around a lot a couple years ago and ended up finding a great deal on a used one (coleman powermate) that's too small for your purposes. Actually, I wish I'd gotten a smaller one.
Anyway, I suggest checking out the 'chondas' at harbor freight. The small ones had great reviews. They changed their engine line up since I was looking at them, but I owned one of the last kind they sold (but on a mower) and it was a total (good) rip off of a honda.
