Have you considered http://www.piatti.ch/? We put in our kitchen 10 years ago and it still looks great and we haven't had any problems. I guess it depends on how intensively you use your kitchen. Poorer quality will show up quickly if you use your kitchen a lot. Have you gone to Ikea and at least one other showroom to make a "hand-on" comparison? That might help you decide whether Ikea is the right choice for you. Also, you should consider planning and installation. We thought we had it all planned out, but then the local Piatti guy came and pointed out all sorts of little but important details (which way doors open, which kind of drawers where, coordinating drawers and doors, etc. Such things can make an enormous difference is the usability and comfort of a kitchen.

Good luck finding the right kitchen!
