Smoker

I currently have and use a large trailer home made smoker. I am looking to get a smaller easy to use smoker that can be left alone for several hours without sacrificing quality smoke flavor. I want to be able to get a real smoky flavor or moderate if wanted. I'm looking at the Weber smoky mountain 22.5 in., the smaller Good One, and the Onyx oven smoker. Which of these is the best choice and why? Keep in mind the prices of each when recommending. You can private message me. Thanks for your time. Suggestions for a better choice than the ones I've found would be appreciated also. A pellet smoker is a choice i have looked into, the only thing ive read that i dont like is some claim they dont put a lot of smoke in your meat. Any input on that would be appreciated also.
