Thanks Raoul & Michael - I have opted for an Aiptek MediaTablet Ultimate II - It apparently has the same aspect ratio as my monitor which is 16:10 rather than 16:9. I am an old boy designer and i am fluent in pencil and hold a black belt in eraser and French curve handling, however I am totally dyslexic with a mouse whilst drawing, maybe the tablet will help, a pen and pencil is more natural to me, but i have also been using a mouse with CAD packages for over 10 years so it's going to be interesting to see what happens - :¬)
