Finally any comments. Nano vs Colibri II. Any others devices I should
look at? (I have got a while to do my window shopping, the prayer
process will still take many weeks.)

You might also consider the EW MicroRecorder - £240 + VAT + P&P.
Its a completely self-contained brick (115x85x25mm, 280g) with an
external puck-style GPS antenna and built-in pressure sensor. It has an
internal, user-swappable battery, takes a 12v external supply and has a
USB connector for configuration and downloads. Both the 12v and USB
supplies charge the battery. Uses an SD card (supplied) to store IGC
files. It is fully IGC certified.

I have one and like it.

Its biggest disadvantage is that the internal battery is NiMH and can't
be disconnected: the combo of NiMH self-discharge rate and the power
drain due to the soft power switch means that I have to remember to
charge it every month or two during the off season. During the gliding
season you never charge it: if you connect it to the glider's battery
during rigging it will be fully charged by the time you derig.
