Anybody...

I'm looking for travel / holiday insurance.
I'm a frequent traveller - europe and middle east I sometimes take my family with me. Since moving to Switzerland I haven't dragged them allong on a business trip, (I'm covered by my employers insurance scheme, they're not). In Holland we had a policy which was renewable on a yearly basis and covered them / us the whole year, which we had to terminate because we are no longer resident in Holland.
We're considering a couple of trips in a month or two.
Any suggestions about where to get something?
I've seen plenty of ads on the internet, can they be trusted? We'ed prefer a Swiss company.
