I agree with this completely. I still have a rusty, dual fuel cabinet smoker but it never gets used. I keep it as it was the easiest and best way to make deer jerky.
I have a Weber performer with the table and gas starter. Bought it for around $300. After reading this site and few others I was interested in a Kamado type and bought the Char-broil kamander for $300. I made my own version of a slow and sear with two charcoal baskets and a water pan.
When I am home I do most of the cooking , tonight it will be filets. I can do a low and slow smoke for 8+ hours at 225 or a hot pizza cook at 600+ with the kamander, it is pretty good at searing also. The weber is great for anything and everything else, especially if you want to play with indirect and direct heat. So what I saved on grill costs I have definitely ate and drank better!
At $300 even if either of these break down in five years I will buy spare parts to fix or buy a new one. I will still be out ahead. Weber has an excellent warranty.
I do see the appeal of the pellet smokers. They seem easier to use and a lot less messy to clean up?
No matter what you choose enjoy! Odds are you may be buying something else in the future. Says the guy with three different grills/smokers, tons of cast iron and pizza stones.
