Don't have a smoker yet, but ready to get started. I've been thinking about getting a GOSM from walmart, they are on clearance for $74. It's the 3405GW model, I think it's only 16" wide. I have seen opinions about the wider model (20") being better, but the price would be about twice ($140). Is it really worth the extra cash for 4 more inches in width ? Can I get quite a bit of meat if the 16" wide model ? Looking forward to getting started.
