pace edwards roll top
I have one I bought in Dec. last year. It works good, I would recommend it. Only a couple negative things though. The thin rubber seal on both sides tries to turn under occasionally. Don't use to much vaseline to lube the tracks like the install says, it makes a real mess on your fingers when you roll the seal back out. Also, no fault of the cover, I didn't attach the web strap per directions and one day when I had the cover open moving my sisters new washer and drier the strap got "sucked" down between the bed and cab. It wrapped around the drive shaft and made a noise and vibration that I can't discribe. Luckily, I was only going 10-15 mph when it happened. It ripped the strap in half. It scared the crap out of me. But no damage done, I just retied the shorter strap back to the top and make sure now that it is not free to wander around on its own when the top is open. You lose about 10-12 inches out of the front of the bed if that matters to you. Good luck!
