As with any of the IKEA pieces, your relative success in cutting the doors will depend on just how careful you are in doing so, and the equipment you use.
The first thing is to start with a brand new, fine tooth blade - the more teeth, the merrier. There are blades made for particular types of cuts, and if you can find one that says it's for fine or finish cuts, I'd go with that one. I also think a thinner blade is better than a fatter/thicker one.
The finishes on
change all the time, and so it's hard for me to judge whether one will cut better than another. What cut well a year ago might not do so well today. A good example of this is the
Abstrakt line - it's nowhere near as good as it was a couple of years ago.
That being said, take your time, carefully measure and layout your cuts, and use the new, thin blade and you should do well. If you want to experiment, see if you can buy a smaller version of the actual door you want to use - is there one available for the wall cabinets that you could use as practice?
