Inexpensive, portable crib recommendation

[sugarpie honeybun]

Can anyone recommend an inexpensive, portable crib (that's not a pack n' play)? I tried looking through some old threads, but am having a difficult time finding recs. Our son is almost 20 lbs, 5.5 months old and will be spending a few nights at our parent's house. The pack n play seems too low (i.e. bending down to pick up/put down) and the mattress seems too hard and thin. He sleeps well in his traditional crib, and I was hoping to find something along those lines.

If this was discussed somewhere, could someone pretty please point me in the right direction?

Thanks!
