Best Hard Tonneau Cover

I am sorry if this has been covered to death but I am trying to determine the best Hard Tonneau cover under $1000. I want a solid cover but either a folding or roll-up.

A couple that I have seen on the net are the

Extang solid fold
Pace Edward Roll top

My truck is a 2007 Double Cab Short bed.

I would like to get a top that taps minimal intall effort and hopefully keeps the inside rails in place.

Of course I am open to other suggestions than those two listed and I want it to be a hard top.

Thanks
Mark

 

I'm happy with the Undercover...see attached pic. You can easily remove, weighs around 50 lbs. and stores on hooks (included with purchase) in the garage.

 

the extang trifold is a good cover and undercover is also a good cover.

 

I have an Advance Accessories Tri-fold tonneau, vinyl covering a hard shell. It locks right into the factory bedrails and takes about 1 minute to install, 30 seconds to uninstall. I picked mine up from a guy for 300, but I think its about 800 retail. I love it.
