Yes, I do. Its super easy when you get into it and I think I get very good results. Plus cheap as chips - its basically sweet black tea.
I got a starter kit about 2 years ago from a health store, which had a scoby in it and have taken it from there. I think it cost about £12, but I'm sure there are cheaper ways of getting a scoby - I've also grown one from scratch from one of my livelier bottles. I think you can probably even get one from a bottle you buy - its the jelly like blob you sometimes find in it.
There is a small amount of trial and error involved, but once you get into the swing of it, it is really very simple.
