I bought mine at Autozone for about 40 or 50 bucks. I can't recall whether they had the $50 one with the lifetime warranty in stock, but that seems like a pretty good deal.
I had one from them in the 90s, and it worked well until the engine was out of the car for 18 months. I wasn't able to use the warranty on that one because of location and time pressures, but I've been pretty happy with them on other items.
OTOH: the replacement for my earlier AZ starter came from O'Reilly's and had problems with the gear recessing out of the way of the flywheel. It caused a screaming sound that was a real mystery to me for a while.
I'd be interested in hearing why, for a cruiser or quasi-DD, you would go with the higher dollar remanufactured ones from ebay or the parts catalogs.
The mini, I understand.
