Depends.

FLARM is approved up to Diamonds only, but Volkslogger is approved up to
World Records.

Assuming anybody still cares about IGC...

I do...

I am running out of badges to claim. Next will have to be 1250km diploma
or a national record. Both are rather ambitious for me in my LS3a, so
there is no hurry. But both would need a VL level security logger. Maybe
I can start preparations in the meantime by praying the Volkslogger back
to life.

In the meantime will OLC accept logs recorded by my old (non-certified)
Swiss Flarm, or a PDA running XCSoar? I still have both of those
options. (FYI you can upload a file with an invalid date header to
Skylines, but not to OLC.)

What level of contest obliges the CD to insist on a digitally signed log
file? I have not flown anything above regionals in decades. If I were to
threaten to pitch up at a nationals could I negotiate with the CD to
accept non-signed log files? (Please sir, I fly in Africa and I promise
I wont trouble the top of half of the results sheet...)

What is the validity status of a digitally signed log file that just
happens to have a date header that is exactly 1024 weeks in the past?
Especially when it is backed by other evidence, like an identical but
unsigned log file from another device which has the correct date header.
This could evolve into a big appeal process for a top level pilot one
day. Maybe I could set a precedent in the meantime.

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.

On occasion when my CAI-302 hiccuped or I goofed in downloading it, I've
submitted the igc file generated by XCSoar on my Dell Streak 5. It is
acceptable to OLC, though not for badges or higher.

As to your question about acceptance of a file during an official event
even when backed by another file from a non-approved device, consider
this: You're working with a bureaucracy (contest officials). When's
the last time a bureaucrat bent the rules just for you?
