Ful-sized portable crib?

Anyone have a full-sized portable crib and/or know where I can find one? We would like to get one for Grandma's house and have been having problems finding one....

Thanks!

Wish I did. DS outgrew the basinett feature of the pack-n-play, and my mother-in-law couldn't pick him if he slept on the bottom of it. Since she watches DS daily, I didn't want a flimsy, rickety, 1/2 size portacrib. We just bit the bullet and bought a second regular crib. We convinced my brother-in-law (her other son, who has one on the way) to split it with us, so it wasn't that bad. I'm not sure what your needs are, but I'm actually pretty glad we did this. Good luck.
