I can do some prgeammjng of my own.

The original, proper VCDS cable is made by ross-tech. They go for £200-250 brand new. There may be someone selling one secondhand. Anything cheaper and it's probably a fake and unlikely to work, or required an older, cracked version of the software. There have been a few forumites who've bought the cheapo ones and then had to buy the proper ones.
