Brien:
If this is a life changing decision for you, you may be taking this BBQ thing a bit too seriously. I like BBQ, but it is not worth falling on your sword for.
Anyway, I think that the welds on my Lang are nice looking, but I would not put them in the same class, as say-- Jane Russell.
Once you are thoroughly engaged in using your new smoker, I am sure you will find that such things are not of great import.
The purpose of the tool, and its ability to perform, will probably quickly overshadow any other considerations. I, for one, like the rustic appearance of my Lang. When you look at it, it is clear what its purpose is. Its functionality goes hand-in-hand with the feel of strength inherent in its design. It just feels right when you use it. That doesn't mean that I couldn't fall for a new BBQ suitor, if the right one came along, but I am sure if you choose Lang-- you will not be left wanting.
Have fun.
