The PBC seems really cool. I've watched all the videos. But it seems like the parts people like are the parts you can replicate. For example, if you like waiting 20 minutes for your charcoal to heat up, you can do that with an WSM. If you like not touching vents, you can do that with a WSM. If you like cooking without a deflector, you can do that with a WSM.
It seems like it really comes down to meat hooks...though I bet that could be replicated as well.
Still, I kinda want one. lol.
