If it's a 2-cycle model, keep in mind that you'll have to mix the gas and oil. Lawn Boy mowers used to be one of the best, I'm not sure how they stand up nowadays, though.
A few months back, I was at Home Depot and noticed a returned Lawn Boy mower for $99. It was still very clean and was selling for less than half the original price. I had to resist hard from buying it. Then again, I had a 2- month old Honda-powered Craftsman mower in the garage which has been great.
