Got an order in for a Red guide, not in stock at the moment but Roger at Bionicon hopes to have them in stock soon. He has some stock in Green, Blue and Pink if anyones interested. If the Red ones dont appear after a couple of weeks might change to any colour thats still in stock. Really looking forward to it dropped my chain again at weekend :x
Going to try a ghetto version made from zip ties and a piece of plastic pipe, might look censored but hopefully stop the chain drop.
I made my own out of a rear reflector mount: see http://www.youtube.com/watch?v=jwze3onhApA
Cable tied to the derailer cable and some heat shrinked plastic inserted for durability. Never dropped my chain since and cost me nothing!
