Hi, my name is Ted and I also had this problem.
I started with a GOSM, took a char-griller offset and McGyver'd it to be a reverse flow, got into ceramics with a Primo Oval XL and each time I got better. On the ceramic, I have aced pulled pork, ribs of all kinds and the elusive brisket! But even so, I dreamed of a big boy offset. Being in PA, that meant a Meadow Creek. I got a sweet deal on a gently used/demo TS120P with inusalted firebox. I tried and tried and tried. Reading, watching videos, talking to experts and the manufacture. Nothing I could do would improve my food output, or give me any ability to enjoy it as an extension of my hobby. So after three months, I sold it. Luckily, I did not lose any money, just some pride and maybe a bit of manhood.
It wasn't the smoker, it was me. I probably didn't give it much time, but at 52, my patience is not what it used to be. So, I am now focusing on making excellent Que in my Primo, expanding my sous vide use and also getting into drum smokers.
I have a Hunsaker Vortex setup (flat black) that was just delivered awaiting me at home. After tasting some fine Que in Kauai at Chicken in a Barrel (Kapaa), I was hooked. I talked to the guy there and he showed me the barrel cookers. The meat was outstanding.
So now it will just be me, my Primo and my Hunsaker. As many have said, it isn't what your using, it is more about enjoying the process and making good food and sharing with friends.
I have been on this forum since 2009 and very greatful for all I have learned. It's Friday, so lets get the smoke rolling!!
Take care all!
