I got the roll up kind, Velcro on the sides and a simple snap in latch by the tail gate. Simple and works, had it for a few years now. It was just shy of $300 shipped, about 275 if I remember correctly.
What truck? I have a fiberglass one for a 2011-2016 6.5 foot f250,350 that you can have for $50 if you come and get it. I prefer the 3 section foldable with me 5th wheel hitch.

I have a Peragon that I love. It's metal so looks a hell of a lot better than the cloth ones and it folds down to a smaller footprint than the metal ones, like Retrax, that use a cartridge to sit in. It also comes right out in 20 seconds. Edit: I did pay about $700, though.
buys brand new truck... apparently should have just bought an SUV if he's immediately going to cover the only thing that makes it distinguishable from one...
