Yepper, I have one and absolutely love it.
It's low-tech compared to a MAK or Memphis, but the control is better than Traeger's 3-position as it's an infinite position style rheostat.
It's a nice cross between old-school and new school. Old-school
in that you it doesn't maintain a set temp; you set the pellet feed rate, so you do have to tweak it for temp as the food cooks.New School
in that it's a lot easier adding pellets than charcoal and you don't have the charcoal/ashes to deal with after cooking. It's also much easier controlling the temp.
As far as portability in a pellet grill, I think it can't be beaten. Even with my Weber Performer, I can load it up in the back of my mini-van and take it. A small 12 volt lawn/garden tractor battery will power it with no problems for hours on end. A long cook is no problem.
We took it to the Church Luncheon back in February to finish cooking a brisket.
The Weber One-Touch Silver
is all you need. The One-Touch Gold will work, but the extra features (which cost more) are literally not used with the Stoven and the One-Touch Platinum is NOT a good design for the Stoven because of how the lid opens.
If you like I can re-post my review of it here later today and am more than happy to answer any questions.
