Not on sale, but a decent price. Homebase, of all places, is selling 3 metres of toslink optical cable with 2 extra 3.5mm plug adapters for £6.49. Great for hooking up the MD portable. Why pay more for glass fibre?
What is the length limitation for optical connections. I'm installing an AV unit in my new extension and I'd love to be able to place my amp at one end of the unit and my dvd player at the other, about 10 feet apart maybe.
