I've had the sport locker box for years. I've been very happy with it. I've never lost my lid since I always lock it. If you forget to lock it you would lose the lid.

The Max is only slightly bigger. The freight to get the one piece box was outragous and that is why I bought the one that you put together. For your Acat I'd expect the regular box to be plenty. However, if the Max is not much more money I'd go ahead and buy it.

I like the Sport Locker because it never rusts or deteriates. I did have to patch it a couple times with some fibreglass but that was easy.

If you get the assemble yourself box make sure you use the backing washers for the rivots. The washers help spread the load. I've seen lots of people have problems that just used the rivots without the washers. The rivots will pull right through the fiberglass.
