My hardware store has 2 Webber Water Smokers. Both much bigger than my ECB. After having to smoke several days in a row on my ECB to get enough food smoked for a large party, I'm considering a new smoker and instead of an offset smoker, I'm now considering just a larger water smoker like a Webber. There seem to be many benefits to this smoker. What are the drawbacks? The list prices I see are $299 and $399 depending on size.
