I saw that. From the pictures, they look like good quality.
When I saw the rolling tray, I thought "nice, but where would I put it?"
Mine is ghetto in comparison, but it's the best tray I ever had, and only $6 at Petsmart

This little kitty dish with rubberized bottom has never tipped, slipped, spilled or been knocked over even at my klutziest and it has enough lip that my meds aren't if I hack out an ambitious toke.
It is accessorized with a liner from a pack of CD's which fits perfectly 1/8" below the lip to keep things moist.
In keeping with the low budget look, you can see that it is due for a bit of ISO.
