I was never a big fan of the chimena. I thought the fire box area was way too small and only offered a view of the fire from one direction. It was hard roasting marshmellows as the door/grate was kinda small on the one I saw/used.
I'm not saying not to get one, but if you have the opportunity, see one in action and decided for yourself if it's the right thing for you before hauling one of em home. I had a few friends get them in the "Great Chimenea Craze of 2001" and they now sit unused in the corner of thier yard I think they can be great, but like Geekd did, try and see one in action first.
I do like the front grate on the one in his pic. Som are very small and not practical IMHO.
