Have you seen one in person. Their description says "Riddling grate system/shaker grate." I've heard of a couple grated ash systems that don't work as well as others. I would want to see their setup before I took the plunge.
Instead of cemented seams, they are gasketed. Seems like it would be an easier re-build, when the time came..

Yep, spend a little extra now to get what you think is going to work the best, and what looks best, and be happy for a long, long time. :)

My tiny Morso has the riddling grate. It's two round grates and one rotates about 90 degrees clockwise and counterclockwise. There's a rod sticking out the front and the stove came with a handle for it. I really like the system since I can just pull all the ash to the front of the stove in a pile, close the door, and shake it down. I've read in a few places that the squirrel stoves with shaker grates are designed to burn coal and/or coal briquettes in Europe and the lower intake opens. So far I haven't found anything definitive and my lower intake does not open, but could be made to open, but I also have no need or desire to burn coal.

The cooker has a more standard cast iron grate and raking the ash makes it fall through. A bit messier, but better than scooping it outside of the stove. As long as the coals are still hot I don't have any issues with ash getting out. Both stoves have a gasket for the ash pan area. The cooker has one door for both openings and the Morso has two doors.

That is what's in both my Dutchwest and Keystone. I like that I can let the ash pile up on the grate if I wish, and stir it down into the pan only if I want to. The Keystone also feeds air to the coals via the grate, through a 1/4" hole in the ash pan housing. If I let the ash build up on the grate, less air gets through, or I can stir the ash down in selected spots if I want more air to fire up the new load in a particular spot. It's not a lot of air, though, compared to what's supplied by the primary air control. Whew, I got a little off track there, didn't I? ;lol
 
I haven't seen the 7110 burning, just on display. But the ash grate system looked robust, which is all I can really say without using it.

The build quality of the whole stove was striking, though. For a somewhat inexpensive stove, the fit and finish was outstanding.
