I see your location is derbyshire???
What is your reason for purchasing a Jetstream, in terms of the market your aiming at??
Have you done much research into Jetstreams or only just started researching??
Eastern use to operate mainly Jetstream31/32 but now operate Jetstream 41, however there maybe a few 31/32 still knocking around. Best bet would be to call up Eastern. They are the largest Jetstream operator in europe.
