Again, thank you.
I had more or less desided for a Jeppesen CR-3 when I read your comparison.
Even not that big differences, the somewhat higher contrast and slightly higher rotation resistance on the APR may make me reconsider.
I have also asked the responsible authority and in Sweden and there are no restrictions on what non-electronic flight computer I can chose from.
Other than that, a new candidate has come to my attention, the ASA E6B Circular Flight Computer. I guess its the same as the others? any one with experience of that?
(I guess I'll be happy with whatever computer I chose)
