I wanted one for use behind my tractor for years, but just could not justify the price - especially when you look at sizes appropriate for use behind a compact tractor. The price is significantly higher than the already steep price for a unit like what is shown in the video.
Several years ago, I saw one come up for sale used a couple of hours down the road from me and jumped on it. This one had a hydraulic winch option, but did not have the hydraulic drive. It had maybe 50 hours of use on it and looked new. I still could not justify it at 60% of the cost of a new one, but bought it anyway. I've never regretted it
