I got a great renewal price from A Plan on my SC insurance today
(£289 with a few light mods) I mentioned that I used the forums and Clare asked me to post on the forum as she'd been so helpful 
If you wan't a quote she can be contacted on 01635 874646
(Clare Irionside) but I recomend getting a price for them to beat first otherwise they don't seem to try so hard! (last week I was given a rough quote of £400).
