go for the worcester although the newer icos's seem to be a lot better than the earlier ones. vaillants are only glowworms with a different badge on

given the choice i would stay away from all ideals! vaillant would be the preferred choice with worcester and potterton in follow. Obviously you pay for what you get but Vaillant are number one.
hope this helps, again only an opinion!

I personally like the Vaillant boilers
but thats only an opinion (and they are more expensive)
