the sound professionals offer the most bang for the buck. I found the wireworld were slightly better tho at 3x the price, and the sonicwave are supposed to be very nice as well ($80). I would buy the sound professionals as the differences to other glass cables were small and the price is right.

also, the glass cables tend to be a lot more flexible than the plastic variations.
