I snagged the roll n lock on Amazon for $1048, which seems significantly cheaper than everywhere else. Honestly that's the main reason I went with it. I was torn between it and the retrax one, but at that price I figured the roll n lock would be worth it.
The install went fairly smoothly. Getting the threaded bars which hold the 4 main brackets to the stake pockets in the corners was kind of pain, and honestly they seem like a subpar solution. Also it seems like the clamps holding the middle brackets are too long, maybe they are for the previous model. I ended up having to use washers to space them out. I can post pics of this sometime this week as I plan to take some to send to Roll N Lock to show them the problem.
Other than that I think it looks pretty good:
