In reply to annna g:
Have you thought about joining the Austrian Alpine Club (UK Section). Membership is about £40 a year and, as well as generous discounts off (some) Alpine huts, it includes World Wide Mountain Rescue cover. Note that it's ONLY that - enough to get you off the hill and into hospital - you'd still have to have standard travel insurance to cover your baggage, cancellations and all that sort of stuff - but that's cheap.
That's what I and most of my chums do.
