There's a guy who's on ebay and audiogon that does the glass optical cables for I think $17 for a 1m and $20 for a 2m. I have heard that these are somewhat fragile, so it might not be a good bet in the field. People rave about them, say they're better than alot of high end coax cables, but I haven't heard one yet to say. Ordered a 1m to go from my CD burner to my DAC and one for my home theatre system, I'll report back if my mind is blown when I get them in...
