Rev-A-Nator

I haven't found any, except a sold one on here (this month.) Everywhere I've checked, none.
I bought 1 brand new, and had it sitting for over 2 years, then traded it with other parts. Dumb move!
Been looking for 1 every since, with rev limiter built in. Saw another type, but alot more expensive. So, I thought I'd post a want ad, and someone might see the heading and decide to get rid of 1 they had just sitting too!
