I just picked up a gently used Troybilt cultivator/tiller at a yard sale. $150 or about half priced. I prefer to turn my garden with a digging fork so as not to breakup the soil structure, but that's becoming difficult. This should help, and if used sparingly should do minimal damage. We had a smaller one and it was great for turning in compost or other amendments. I also got a new handle for my digging fork @ about $14 at Ace instead of $35 for a new one.
