After a few months with our Smoke 51 Duos , it i is time to get something a bit better. I am looking to refill my own while following the Keep it simple stupid rule of thumb. I have narrowed it Down to the Janty and Screwdriver on my short list. I am leaning toward screwdriver because I don't need to get in various parts form different suppliers. Any others I should be seriously looking at that I might have missed? Yes I have been haunting the forums steadily working on sorting it all out. My Brain is cooked and I plan on ordering the end of this week.
