Open Question: What private health insurance can I choose with pre-existing conditions?

My family cover has just ended and I now have to get my own personal insurance. I have a pre-existing condition (nothing major) but I want it covered for in case it flares up. My current insurers, AXA ppp, have ask for an arm and a leg. Are there any other insurers that insure me for my pre-existing conditions or are able to act as an intermediary for AXA ppp and offer a better deal?
