You'll probably get a biased opinion here, as I'm sure you will in the Bradley forum. Just do some research, look at the plus/minus of each.
I've really tried over the years to keep the posts here from being negative, since that just gives us a certain perception (over the years other forums have not been as nice to CS, but that's another story). I don't get paid by CS, so I don't want my views being perceived as a shill for them.
Look at workmanship, customer service, support (forums and direct with the company). In the end, you'll have this forum telling you buy here and over there, they'll tell you buy that.
That's wrong, key is to focus on what you want to do and try to understand the capabilities of the smoker. Ask an owner, of course they'll tell you buy what they have.
So it's tough.
If you read enough of my posts, I try to understand the needs and help you find the right fit.
The bradley does a decent job on cold smoke as does the CS. You just have to adapt to those smokers. If all you're wanting to do is cold smoke, you can make any smoker do that, just get a hot plate and some sawdust. In the CS, you can use Sawdust or pellets.
The CS is insulated with 800 degree insulation.
That being said, I do try to point to relative articles when I know of them.
Here's an article by the owner of the Charcoal Store:
