I bought a load in bulk and have been making patch cables and selling them on ebay at different lengths (10cm, 15cm, 30cm, 50cm and 1m). If anyone is interested I can make custom sizes too. I stuck an advert up on the 'affiliates' page - 10% discount (i.e. 10% less than the ebay price). These little jacks in my opinion are just as good with regards to sound and are very low profile.
