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.
