Our kit was about $2K. NOT including gravel we had to buy for a pad, because we have very few level spots of land around here.
Later we needed a replacement piece, so that was another ridiculous price for a piece of PLASTIC. We DROVE to Farm Tec in Iowa to pick it up versus the INSANE price for shipping it a few hundred miles.
FarmTek’s Growspan Elite is a little over $4k now if you buy the steel base. That is plumb loco.
Our money isn’t worth the paper it’s printed on.
