Just installed an IKEA kitchen here in CH but in an occasional use chalet studio. They are good quality for what you pay. Probably good for at least 10 years. Be aware of the following:

Buy a worktop separately as the IKEA ones are limited in choice and the coating appears a little thin, fine for my needs but not if you use it daily. The taps should also be bought separately eg go to your local plumbing merchants. The sinks also are quite thin so the taps are a bit wobbly (my plumber warned me about this) so again, select from your local pumbers merchants.

The fridge IKEA fridge is in fact Whirlpool and is very good. The cookers and surface hob are also good quality and with a good deal of options.

The instructions and support you get from IKEA are excellent and the planning software (you can upload your 3D plan to their server to simplify things in the store) is also good and easy to use.

In store, we were given a number to wait for a kitchen specialist and a free cup of coffee while we waited for the number to be called (they called our handy when they were ready). Very helpful and knowledgable assistant too (IKEA Lausanne)

All in all a very pleasant experience when compared with the same thing in the UK buying "quality" kitchens.

Hope that helps and sorry if it sounds like an IKEA advert... just speak as I find.
