My experience with the PlotMaster was less than impressive. Given the fact that our soils are clay, the PM took forever to break the ground. Also, it was, and may stilladvertised to be a one-pass planting tool. No way.

No experience with the Firminator. I saw the Summit 4-wheeler equipment and it looked good. In my opinion you're better off with individual pieces of equipment than spending a fortune on one of the PlotMasters.
