Hi Vic. Thanks for joining. Once you get to know its individual quirks no BBQ needs to be a bad BBQ. They may not all be good all-rounders however they will usually have their own niche.
The Azuma will certainly be good for cold smoking and should also be fine for most other BBQ too. You just need to learn how to regulate the cooking temperature inside. When you first use these types of BBQ the tendency is to get a nice raging fire going in the fire box - then wonder why the meat comes out incinerated on one side. Use a relatively small fire and learn how to control it using the air vents to give consistent cooking temperatures between 110C and 180C and you should be able to produce as good BBQ on it as well as anyone.
The first thing to invest in though is a good twin probe digital thermometer so you know exactly what the BBQ is doing. The Maverick ET-732 is a good inexpensive all-rounder.
There are a few regular members on here from your general area. Post any questions you like and we will be happy to help where we can. You will also have the combined knowledge of the US smokers on here to help out too. I hear they BBQ a little over there as well sometimes
