I have the 3D-WiFi with the Smokin-It stand... it's a great height, sturdy, and rolls easily enough. Beyond that, I don't really like it for the following reasons:
* The shelves on either side are worthless to me 99.9% of the time. I need a shelf that opens up directly in front of the smoker, not on the sides. Because the shelves hang on the side there are "posts" that stick out on both sides. If I take the shelves off then the posts will be there to run into and catch on things. If I want to haul the smoker and lay it down the posts keep it from lying down. I'm honestly thinking of cutting the posts off and just doing away with the shelves entirely.
* The space under the smoker is just wide open on all four sides. This means that anything and everything blows into that space. It's never clean. It's pretty much a completely useless space. It needs to be closed on the back and both sides. There should be a shelf on the front that doubles as a closure when in the down position.
* There is nothing between the bottom of the smoker and the open area of the stand other than the drip tray. This means that if the drip tray overflows or you spill any when removing it then you've just made a mess of everything in that space which is just one more reason to not put anything in that space. The way it's designed, it's a pain in the ass to clean up as there is a ~1" raised lip all the way around the bottom.
If I didn't already have the stand, I would not get this one.
