My backup vario in my current and my last glider has been a Westerboer with pressure sensors like these:

The one I have has a lovely tone - much nicer than Cambridge - and it indicates in absolute synchronicity with my Cambridge302. They both are on the same total energy probe. I prefer it when working really weak lift.
They sold for about $500.

My old backup was a Westerboer 910 which I got after using a 921 for a few years - awesome varios!

I now use a 1020 setup for electronic TE compensation - and prefer it to my SN10 (TE probe).

I really think that until you get into the top end (?) Butterfly or S80 varios, the Westerboers are the best.

Or maybe they just work better in LS's... ;^)
