Ok - so the impression I get is that while 'buying stuff' (particularly food and eating out) may be more expensive, along with extra charges for healthcare (which we kind of pay with our taxes anyway in the UK?!) I guess the decrease in tax in CH levels it all out eventually....
So, if I can find the 10k required to move myself, and sort out something to do with my flat (rent, sell?) then you will probably be seeing me very soon!
Thanks for all your help guys....
