Not everyone can afford a top end blower, and of the ones he listed I would definitely go with the 350. I don't belive they even make the 150 now, but they do still have the specs on their site. The main difference in them is that the 350 is a strato-charged engine (like all their pro grade blowers are), which means better on fuel and lower emmisions.
For the size place in that pic, a 350 would be more than enough blower.
