I have been looking for a used PHD for some time. What I did was read lots of posts on this site and wrote down the brand names of those PHD others were using. I then researched these for a price new and if it would fit a cat 1 tractor. Last week I found one on Craigslist, a Howse PHD45. I called the guy and he said he had only used it to dig six holes and had no use for it anymore. He was asking $350. They list for about $615. When I saw it it looked new, the black paint was still on most of the auger. It may not be a top of the line model but I believe it will serve me well since the soil here is sandy with light clay. Since these are heavy you should consider building a stand for any unit you buy. I found on this site that looks simple, three treated 4x4's. The PHD will hang on the top horizontal post, lift PHD, remove post and off you go, back up lift PHD replace post, lower PHD and you are all set. When I have questions this is the place I look first.
