First time posting but have been lurking for some time. I have been wanting to get into smoking meats and fish and was looking at buying a smoker. I have read numerous threads where people suggest building one. What are the pros and cons of a drum built smoker compared to a store purchased smoker? What is the advantage of a horizontal vs vertical smoker? If I was to build one I like the idea of a stainless drum. Is stainless a better option than a painted steel drum? Also, does the stainless drum require any painting at all? Sorry for all the questions and any recommendations are greatly appreciated!
