Just renewed my insurance with Adrian Flux, found the to be by far the cheapest quote wit the best cover, i used them years ago (when i was young(er)) when i had daft cars like sierra cosworths and found them to good with younger drivers too, make sure you have done your pass plus and are a member of a club as this will help discount your premium.
I got my 1.8 freeby when i was 18. Went with ecarinsurance.com or somethink as i could pay monthly and not be tied in. Got a no claims off em as well. Worked out at just over £3000 for my first year of driving.
It's worth getting a quote both for fully comp and third party, fire and theft. My fully comp policy was actually CHEAPER than a third party fire and theft policy with the same insurer! That was with Direct Line though. The only reason I'm still with them is because I transferred the policy from my old car to my Landy. I hope to go with an insurance company that caters more for 4x4's next time.
