Always go for a condensing boiler if you can - they'll save more in the long run. Can't give you any idea of running costs as you don't state house size/type/build etc. If you want to save money in the long run, had you considered a ground source heat pump? Runs at roughly 400% efficency, whereas the best you'll get out of a condenser is 95% ish.
