Propane Fire Pits

In my rush to book a campsite I had booked a site without a wooden fire pit.

I checked the Park staff, and they said a portable wood burning fire pit cannot be used at a site without a fire pit, but I can use a small propane unit.

What ones out there are recommended? Basically it's my kids and I, just for roasting marshmellows at night, smores, and general atmosphere.
