With something like a Roor, most of the price is in the name- the workmanship is solid laboratory-glassware style but unspectacular. I personally would not spend that kind of $$ on a mass-produced type piece. To be worth over $200 to me, a piece needs to be:
-Functional
-Unique
-Obviously handcrafted
-Show significant skill in the art of flame-work
-Local is a big plus
