Can you get a combi that has an integrated storage tank? Our old vailant did something like this, so at least it would start shoving warm water down the pipe as soon as it was called. Still meant a couple of basins worth of cold water getting ditched before it got warm; I just gave up in the end and only used cold water for anything other than a shower.
Combis tend to be installed in weird locations because their small size allows it (think ground floor kitchen / attic / opposite side of house from bathroom etc) so the epic pipe runs required + the lower pressure means a wait measured in eons.
