I'm not sure what you mean by this, but easy mixed/difficult scrambles might be grade I and II or II/III mixed routes? In which case you will probably find a mountaineering/walking axe paired with any type of ice tool with a hammer will do you fine, as opposed to two matched tools. You'll spend a lot of the day just using the walking axe on it own on easier ground, hence a mountaineering axe does this better than half a pair of ice tools.
Get yourself a nice axe with a decent head and then whatever second tool you can find for a bargain.
