For me, it was never about zero available, it was more about what quality and strength per pound per dollar was there.
Many of the available ones are too heavy, or too small, or too expensive. I eventually tracked one down that should be light and strong. It will be a couple of weeks before I can pick it up from the dealer. I'll do a review and post pictures.
Another problem for me was places like Homestead only made the clamshell style, but I prefer the root style. If I'm going to spend thousands of dollars, I will get what I want, not what they have in stock.
