Between these two...

Hey cesar, well you know mostly what I think about both horns.
The only thing I would add is that the King is a much more compact horn, where as the Miraphone you are looking at is much larger( in terms of bore size) I believe (dont quote me though) that the King has around a .687 bore. although both are considered 4/4 instruments I would say that you'll find the king a little more compact in sound and the miraphone more open and broad. Still think they are both great horns... also consider if you prefer pistons over rotary or vice versa.
