I've been considering the AS. One issue is my fireplace lintel height; I think I would have to cut off the legs and alter the hearth in the area of the handle to get the ash door to open all the way. The setup would look like arse..it'd be a steel box sitting on the floor. 
Another issue might be that, from what I'm reading, the AS likes a little more draft. The Fireview and Keystone will run pretty well on under 14' of stack. I have 16' of insulated liner up through a masonry chimney, so that is only one 90* turn in the tee, about 8" behind the rear-vent flue outlet. Maybe it wouldn't be a problem..?? I guess I could always add two or three feet onto the top but I'd rather not..
