I cut my smoking eye teeth on a Black Diamond which is the predicessor to the Silver Smoker. It's a great pit. If you didn't pick up the Thermometer for it run down and get one. There are a couple of mods like the baffle and stack extention that you might want to look into. Double check your stack, the new ones we are getting in already have a longer stack so you might not have to do that mod.
