I am investigating options for a Vac-pot/siphon bar.  The Hario halogen would be sweet, but costs and arm, leg, and firstborn child.  I also have doubts of its durability in a commercial setting. 

I found a Canadian site offering a Gas Top siphon heating station, made by a company called Yamaoka I am assuming from Japan. 

Has anyone seen or used this before?  Can you speak to the quality and performance?
