XP/Agile Companies?

My contract with my current employer is just about up. The projects I was hired to complete have been deployed very successfully and are stable so I am starting to look around for a new contract. I am really excited about the possibility of getting onto an XP/Agile team since I have been reading a lot in this area and would love to gain some practical experience.

Does anyone know of any companies that have XP/Agile teams that might be worth contacting? If so, then I would really appreciate a heads-up, via my blog or kevint at gmail dot com. I am looking preferably in the Johannesburg/South Africa area, but I am open to other possibilities...!
