I don't have one but I have been looking at them too. Agile seems to have a decent reputation. The new Fender Pawnshop Bass VI is an alternative although not cheaper. Until a couple months ago Rondo had the Argus in seafoam green. It is possible that they would get more colors in some day. You can email them, they have always responded quickly to my emails. If you search on Rondo for 627, 727, and baritone you will find some 27 inch baritone guitars which you may or may not consider to be alternatives. Other people make baritone guitars too. Schecter has made some bass VI-like instruments recently. I am not sure if they still do, someone else can comment on that.
Eastwood makes the Sidejack Baritone and Bass VI in 28 and 30 inch scale respectively. Fender makes a Blacktop Baritone Telecaster in 27 inch. There are probably more, those are the alternatives I am somewhat familiar with.
If I can find a new job soon I am interested in getting one too. The Argus, Pawnshop, Baritone Tele, and the Sidejacks are my short list. Good luck with your search!
