ECOTRIC and other off-brand turnover ball style hitches

I had always intended to put a B&W turnover ball hitch on my 2002 Silverado 3500 DRW. Welp, I dragged my feet for 14 years and now I'm paying for my procrastination. Not only have prices gone up but the B&W model that fits my 22-year-old truck is getting hard to find.

Curt makes a hitch that's a little less expensive than the B&W, but there are also some knock-off brands on Ebay.

This is a long shot for sure, especially on this forum, but anyone here have any experience with other brands of turnover ball hitches?
