You could also build your own. It's super easy and a fraction of the cost. I wanted a custom fit to maximize the gallon capacity for the tight space under my cabinet. Here is mine, holds 7 gallons and is a perfect fit under the cabinet. Even picked the color to match my sump.

No concerns about the baffle failing? I have one of those sump kits with the plastic baffles. It's difficult to get plastic to stick to glass (as opposed to glass baffles against a glass tank), the only reason I'm not concerned about my baffles failing is because there's a generally equal amount of water on both sides so the net pressure on each baffle is minimal.

(If I ever build another sump, it'll be with glass baffles.

The problem with acrylic sheets in a glass aquarium is a raised baffle falling. The silicone caulk itself has plenty of support to hold a baffle in place horizontally. We used to get around the vertical support by cutting two small 1" squares and silicone caulking them underneath the raised baffles right up against the glass. This way the baffles weren't held in place solely with caulk and actually rested on the 1" squares.

I remember a fellow reefer plowing 2000gph through his glass sump with acrylic baffles for a week to see if it could take the pressure. Worked without any issues. I ran the same setup for years with nary a problem.

I hadn't thought of that, but it makes sense. This is the baffle kit I have, which incidentally, has that feature built in. You can see the end panel (that creates the return chamber) is propped up, so it can't slide down.
Also, that panel and the one next to it are separated by two plastic parts that hold sponge filters. Even when I take the filters out, I leave those plastic parts in. Since there's a height difference (in water) of several inches across that section, the high side would have to knock over both baffles.
