Who has a little Wonder Parking Lot blower? I have been using an 8hp for the past month (borrowed) Today, I found a 5hp with little usage and bought it for $250. It seemed to be pretty powerful, but I haven't directly compared it to the 8 Does anyone use the 5 on parking lot? Happy with it? I figure I can't really lose. $250 is cheaper than a backpack....and a new 8hp is just a little less than $1000 here.
