I have an SnP, It's OK. Made a lot of modifications to it that definitely have taken the price over $200 and its still only semi efficient. I broke down and took on a project smoker in early December, had it working in January and haven't used the SnP since. It's an air compressor tank that I built using guidelines from UDS builds and a little creativity on my side. But in all the research I've done on UDS's, I say if you want to avoid gas or electric, build a UDS if on a budget, and If you've got an old standing air compressor tank laying around, send me a PM. If simplicity right off the bat is what you're looking for, I say go electric. It's pretty much an outdoor oven you can smoke with. Hope this helps!
