Hey there. Same here. I've put my hands on it and it's a solid cooker. You can tell right away as when you go to lift the door on the cooking chamber you have to give it quite a heave !
This is coming from a guy who owns a 1,000 lb 24" X 48" offset pit. I think this pit will hold temps pretty well. If it's what you're looking for and within your budget I don't think you can go wrong with this pit unless of course you can score something on craigslist.
