I built my own garbage. I went down to the local steel supply house and bought box beam that slid into each other. The basic size was 2X2 inch. It to length and welded at home & away I went.
In the end it was cheaper than a stand @ Summit racing and more run to build myself but the one at summit is a huge time saver and comes ready to assemble and test your engine right quick.
Legendary member, Tony 70AARCuda IIRC the screen name listed up his be purchased from Summit. Pretty neat and nice. A little pricey? Yea maybe. Cutting and welding your own is a skill set most of us have. If you don’t, or not into building your own, Summit is your place.
