Anyone else ever used a Baretto rototiller? If you haven't, see if a local rental yard has one. Its a hydraulically driven tine and wheel walk-behind, and weighs about 550 lbs. It makes Troybilt feel like tin foil. Even the front bumper thing is about 5/8" thick steel. I rent them for about $100 per day from United Rentals. New - to buy - somewhere around $5000 I think. One of the best items I've ever used. Excellent center of gravity. 13hp, but I think there is a 16hp too.
