Check this out! I picked this up off CL from a guy who said it came with his house when they bought it years ago and that they never used it. Well, the previous owner before him must have also only fired this up a few times because its in fantastic shape with no soot at all on the lava or logs. When I called he literally said "I know I'm giving it away but I just want it gone!" ... well sir, I am glad to help!
He did hook it up to the NG line and it fired right up no problem with nice big flames! There are a lot of ceramic logs and they are all different sizes so it looks quite realistic IMO. The complete unit is a tank and weighs about 140lbs, but has really cool wheels built in that you can tip it onto for easy maneuvering (pic 3). I will try to get some more pictures of it running at night once it stops raining...
