This one is a different model number than ones on amazon. What's the difference and does any one have the one I linked?
The link you show is a late model 2.0 Smoker. On the later models, they moved the exhaust opening from the side to the top. Also in the later models, I "think" all parts are replaceable like the new 2.5 models, whereas the models before it weren't.
The water pan is the main difference.
The Maze will work in both.
If you have a Sams Warehouse nearby, I would opt for the newer 2.5. They are $329 plus they have legs whereas the others don't. I would also get the extended 3 year warranty for $30 since Masterbuilt only has a 90 day warranty.
Yes, I would spend the extra $30 because the 2.5's work better with their oval water pan and seem to be more problem free. I have had both the 2.0 and 2.5 and the 2.5 wins hands down.
