Kanstul Trumpets are well respected and I know several professionals who use them.  Their tubas are well made and, I believe, sound very good.  I was also interested in the Kanstul that was on that auction site, but am not willing to buy a horn without playing it first.  I have never played a Kanstul tuba, but I have played their marching tubas and Contrabass Bugles. If their marching instruments are an indicator, their tubas will be excellent instruments.  
2 things of note on Kanstul tubas:  1.  Unless they have changed, they have small bores (.689) and big tubing, much like older American tubas.  2.  They do not have 5th valves.  
I have only had positive experiences with Kanstul instruments, but I would still see buying one as a gamble because they are such a newcomer to the non-marching side of the music industry, at least in terms of professional tubas.
