It has a tick and a cross, and ABCD buttons though.

Indeed :-)
Looks reasonable, display could be bigger but sadly they are not
exactly doing 15" touchscreen TFTs at that price point as yet :-)

Now downloaded :-)

The CPC offering is 9561UK (ungraded), the 9651EN is the grade 2
panel; EN meeting new EN 50131 and PD6662 requirements (Grade 2).

Actually the usability of the CP8L is easier with Full/Part set buttons (like
Veritas 8) and has Yes/No answer buttons which makes things easier.
Both are good systems, however that swings it back to the CP8L.
