For 50-60 bucks per corner, I would probably spend the money and buy from a company that has a lot of experience making them and has a reputation for producing quality products. There are already several well known producers of DIY beadlocks for that price or close to it. I'm not downing you guys at all because I am sure you are very qualified. If you want to sell very many of them, you will need an edge that sets you apart from the rest of the producers. Just my opinion.
