just renewed with Devit, via 
www.quidco.com  1994 900 Superlight, TPF&T.  Clean licence and 37 years old, B63 postcode.  2 yrs NCB £75.  BUT do it through quidco and I should get £30 back.  So it's £45 for the year!
 I did it through Bennetts like this last year.  Policy was £80 but I got £20 back after a few months (if you don't know about quidco then check the website out) so it cost £60 last year.
 Some benefits of getting old with an old bike!
