Never heard of search tempest, but just tried it and it looks great! found a JD tiller I may go look at, not far away. $600 for a 6' tiller, needing a little work. Would save a grand if it is as he says...You have the advantage of not needing it right now so just be patient and something will turn up. I use apps like "Search Tempest" to search all of CL when I'm on the hunt for something. Sometimes I find it a few hours away, but if the price is right my time is worth it.
Mine is also a KK and it has held up well. I just use it for my personal garden and to help out a couple of neighbors so it really doesn't get much wear.
Thank you.
