I installed the ROLL-N-LOCK cover. It is a roll up cover. It has worked well for me so far. Keeps everything dry. When I received the cover, the top to the canister was damaged, it had a small bend in it. I called and they sent me a new one in 3 days no questions asked.
I did much research on what I wanted, and it came down to a Pace or the Roll-N-Lock. I chose the Roll-N-Lock based on seeing both. Nothing wrong with the PE but I just liked the RNL better.
I ordered from this place because it was in the mid-west. http://www.web4jnj.com/
Hope you find what works for you.
