Hi there....
Here is a good list of organisers:
http://www.biketrackdays.co.uk/dates/organisers.html I'm sure the guys here will recommend either the CSS or ESS schools but I've read very good reviews about the Mick Boddice school and will be giving them a try during 2005 (the sooner the better I think !!!)
http://www.boddicedarleytraining.co.uk/ The bikes are included - I've seen good things about the RH school and always wanted to ride Donington but the track time is limited and your have to do the 'starter' class BEFORE being able to move onto the Fireblade school.
Good luck and - WHAT A GREAT WIFEY !!!!!!!!!
