I have a borrowed 4' tiller of unknown manufacture. I will be returning it soon and am looking to replace it with a 5' model of my own. I would prefer to buy used, but will go new if I have to. Are there any general opinions on which models are really good values? I have seen and used the King Kutter brand and they seem to be decent units. However they are $1100ish new. I would like to spend half that. Anyone know where I may find some nice used units?(I have checked our classifieds with no luck.
