It looks like they have gone up on their price.
It's now $249.99, I bought mine for $199.99
But I'm pretty sure it's this one.

It was foldable, but you have to assemble it when you get it, I didn't put any of the foldable things on
and bolted the frame solid.
Once the 3/4 ply is bolted down on top of the frame, it is very solid. But still light weight.
I wheel this around by hand from my back yard to the front to hook it to my vehicle to go to the field.
We looked at various options, including buying a small enclosed trailer, and this was the cheapest way to go
I've been very happy with it, it serves my needs perfect. There's room in it to haul a 4-wheeler or couple of dirt bikes
if you pull out the slide in shelf too.
