Which electric smoker would you guy's recommend that's under $300? I am just going to be using this smoker for dinner for me and my wife. The most I need it to hold is maybe 2 racks of ribs, or a 4 pound pork shoulder or a small turkey. I've been mainly looking at the Masterbuilt series 30 and 40 inch but i'm thinking the 40 inch is probably overkill and i've also read the heating element in the 30 inch isn't good enough for poultry and would make the turkey and chicken skin chewy. Thanks for any help.
