I left it open to interpretation, in case someone replied with something I didn't think of. For example, last time we had a thread like this someone pointed out wind noise which I never thought of, but what a huge deal that would make to me. I think I ruled out soft covers then.
I guess I'm looking for one that makes the least noise, keeps the bed cleanest/driest, looks the best and functions easy/well.
I was in love with the paragon. The idea of color matching it to the bed made it look the best, it looked really easy to use, it didn't block the rear window when folded all the way up, and if you needed more space, is looked really easy to remove and put in the back seat. I went to go order one and the shop told me they wouldn't order it for me and if I brought it to them they were going to charge me $400 to put it in because it was impossible to get lined up. They said the last one they did took an immense amount of time and labor to get lined up and it fell out of alignment shortly thereafter. They said it never opened all the way, never closed all the way, didn't move easily and leaked like a sieve. And they are pretty pricey.
They are pushing the Bakflip mx4 and the Retrax. I know a couple people got really good deals from vendors on here for those two. I guess I was just looking to see if anyone got a good deal on one that they've had really good experience with.
