I picked one up 3 month ago and had no issue with delivery. Just because they are out of stock does not mean going out of business. Building on demand is a good way to lower carry costs.
Thanks for the clarification. I did misunderstand your interpretation. I would think they would take down the links if they were moving away from the products. Perhaps they are just creating cashflow during the tough times. While I agree that newer shifters provide the same capability as a total package, they tend to be at a higher price point so having this option is nice when on a budget (me).
I bought mine because it allows you to retain the factory shifter. I don't track my car, it's a convertible, so I don't need a better shifter and I wanted to maintain originality.
