Those of us who prize, or long for, an exo terra... Our prayers may have been answered! I was scouring eBay in my lunch hour looking for a glass viv to rehouse my mice and found this!

It looks and acts like the exo terra large and wide but much cheaper than their current retail. Admittedly it's still not a bargain but I think it may actually be better than the exo terra as it has some ventilation on the sides. The front lip also doesn't appear to be as deep which is a bummer. I'm still umming and ahhing over whether I can justify the outlay for the mouse's. If I make the leap I'll let you know.
