If your aircon works, but only needs a top-up then I found this, it may be worth considering. http://cgi.ebay.co.uk/ws/eBayISAPI.dll?Vie...item=7968252650 I have emailed the seller and asked if there is a stop valve on the kit so you can add it a bit at a time weighing the kit as you go, so you don't over fill the system. I await his reply.
