I gotta jump on the Bakflip pile
as I love mine!! Thanks to my fellow forum members who steered me into such a great cover.
Is it more money....yes. Is it worth the extra money....I think so. The ability to quickly fold up in sections, and secure it in the up position is quite choice all while standing on the ground, and not having to climb into the truck bed. I also like the idea of being able to lock my tailgate, and not worry about my gear. It's water tight (when installed properly), pretty easy to install yourself, and looks great on the truck.
I bought mine on eBay at a good price, zero tax, and free shipping. Registered the unit with Bakflip Industries after the install, so I'm all warrantied up too.
I too live in NY, and the winters up here can be brutal with all the snow we get. I can't attest to it's performance yet, but I'm predicting good things from I've seen so far.
