I got that playpen at Pet Supplies Plus for, like, $15. They do tend to jump out, though, especially Jack, who jumps out of everything, even the bathtub.
It's not very big, either. My roommate and I tossed all 8 of our boys in there and it was like a massive rat swarm. Three of them managed to climb out at once before we decided it was time for something bigger and taller. We took some wood planks from the side of our house (we live in a trailer, and the previous owners renovated it, so there were basically thin pieces of wall left over by the shed) and made a little playpen for them. It's proved to be a much better choice, since now we can actually turn our backs on them for a second without one of them going missing.
I woulnd't reccomend it. Instead, I would reccomend you go to PetCo and bought a larger playpen, like one for ferrets, and line the interior with some thin sheet metal or something around the bottom so they can't climb up the sides. The bigger ones can get to be around $60 and higher, but they're probably worth it. Or you can just get some 2-by-4's and make one yourself!
