I have an Access cover on my F150 as well. Looks nice, rolls up nice, looks like no wires or battens across (it has 3 battens though, but they don't really look like they are there when its on and pulled tight).
Installation was so easy, took maybe 15 minutes, including unpacking the box.
My only disappointment is the plastic pieces in the latching system. If your tension isn't set correctly, you can crack them in cold weather. Would much rather have a small aluminum latch there. The upside, the parts to fix this aren't that much.
I think I paid about $250 for it in 2008. Looking at prices now... WOWZERS...
