Machine has rebuilt engine, new head, new axle seals, pro paint job, yada yada. Owner says it is tight, runs great. Wants 7000 bucks. It's a 29 HP engine. Question... Have these small engine machines outlived their value and been upstaged by higher HP machines that have more snot and ability to simply do more? I'm a homeowner, don't need a pro machine, for sure. I've been looking at some other makes, notably Thomas, Ford ( supposedly the same maker), but find this process difficult as far as buying. Anybody have much to say about the 643, or whether the 7k is simply too much for the machine? Thanks, happy new year Mike Connecticut
