hey folks. i am a moderator on a motorcycle forum i am on. i have my own section, for bbq, on there. the forum admin made a post to me about what should she look for in a smoker. i have gave her a link to this site before, but i know what she wants is for me to explain the different types, and what to look for, so everyone can read it. she knows i just started bbq'ing, and am not an expert. so i need some help here on explaining vertical vs. horizontal; and LP vs. electric vs. charcoal/wood. any tips?
