Word of warning. If you have young kids, painted doors will chip up very badly. Also, beware the quality of the painted doors, as they also don't like splashes on them around sinks, dishwashers etc.
Finally, there are plenty of kitchen suppliers out there selling painted wooden doors that don't tell you that they are not solid wood underneath the paint, but some form of composite board. When I was looking for kitchens recently, almost all those I pushed hard on the matter admitted that their high quality painted doors were in fact MDF or equivalent underneath. So make sure it is actually a solid wood underneath, and one that can actually be dipped and repainted in the future if so required.
For what it's worth, with 3 youngsters we went a good quality MDF/Foil wrapped kitchen from Magnet, did us a very decent deal on appliances and granite worktop, they clearly are making their margin on the units to do this.
