I currently use an SDI C3 which has all the vario functions
and, if linked to the GPS a final glide computer as
well with continuous readout. I find that it is as
user friendly as any complex vario and has all I need,
and you do not need a PhD in computer science to set
it up and use it. I purchased mine for £500 3 years
ago (SH). The SDI C4 is supposed to be better but a
little more exp[ensive. I have used a Cambridge and
an LX5000. For simplicity and clarity the SDI wins,
the only drawback is the lack of some features.

This instrument needs some attention, and we are wondering
if its time
to replace it rather than spending money on something
outdated.

We have a separate GPS/logger/nav display system (Garmin
89, EW B,
Compaq 1550), so we aren't looking for all the bells
and whistles.

It would be good to have a system which didn't need
a flask connection
for the vario function, and which gave us a flight
director (Told us to
fly faster or slower)

We are thinking of spending about 700 GBPs, 1200 Euros
or 1200 USDs.

Any ideas, anyone?
