I have a SmokeVault 24" that I've been obsessed with since the day I got it, fortunately my wife loves the finished product so she tolerates it well. I've done a few things to the grill to help keep the temp stable, however there are times when automating the process would be nice. Lurking through the forum, I saw there was a product (sentry valve) that would automate the adjustments to keep a stable temp. It seems that the vendors that sold it don't have it listed anymore; but the other problem is that it was for propane. My Smoke Vault runs off of natural gas - it is nice to never worry about the tank running out mid smoke. Any suggestions? Few co-workers have pellet grills that they "set and forget" and I'll freely admit that I'm a bit jealous of that ability.
