I got the "cheaper" stuff at Home Depot when I did the renovation in my attached garage.
I had one of the hooks get caught on the garage door and it bent the heck out of the hook but the MDF Slatwall was fine. I also had the garage door catch on one of the baskets I have near the door to hold car washing stuff and it did break a little piece, so I moved the basket over just a bit to a good area. Incidentally, the piece did not come off...it's kind of hinged by the laminate.
At HD, it was about $40 for a 4x8.
I do not hang hundreds of pounds from each hook or basket, but it seems to be more than strong enough for what I am doing. Plus, in this smaller garage, has given me the ability to move things around, even wall hangings to better organize. We have a local retail store called Gershell Brothers that sells all kinds of hooks, baskets, shelves...etc
