Already posted my support for the Solo but with some of the comments I wanted to address some of the concerns.
I can see where the Solo is not ideal for a larger group because you would be sitting further away and the sides would block the view. In our case 2-4 people is our normal group size sitting around so we sit closer and are looking down into the fire instead of across to the fire. The one time we used it for a much larger group because everyones wood was wet accept my little chunks of wood sealed in a plastic bucket. We just feed more wood in to keep the flames higher.
Since I cut up scraps from wood projects it is all kiln dried so no bugs, not a problem transporting it to areas that have restrictions. If you don't do enough wood projects to feed the stove I'm sure if you ask around someone will give you all the scraps you can use. Just don't use pressure treated, plywood or particleboard scrapes, bad fumes.
Someone mentioned easy cleanup, depending on how long we burn the Solo but our normal fire generates about a 1/2 cup of dust when I clean it out in the morning. Easy to dump most anywhere and then wipe out with a piece of paper towel.
I don't sell Solo stoves, just a happy owner. There are plans online for making your own smokeless stove if your handy.
