I have to agree with Ladymom. I would avoid putting a puppy in a mesh playpen until the puppy is older or can be supervised the entire because most puppies are chewers.
I think the seabreeze pens are great. I would get one that is at least 24 inches high.
I also have a mesh pen from Ebay which may be similar to what your looking at:

Its been great for travel but I don't use it too much at home because I worry my pups will chew right threw it when I'm not looking
