I meant to respond to this earlier.
We recently renovated our kitchen and used IKEA cabinets. I LOVE them.

(Now all my friends want them, too.)
I shopped around for 5 years. These were the first ones I saw and the ones I always went back to. They're beautiful, good quality (coming with a 25yr guarantee), and exactly what I wanted.
We used a design service that works *with* IKEA. They're an independent company but work exclusively with IKEA. (They are quite busy; in fact many of their clients have oceanfront, exclusive homes.) They helped us design it and gave us plans that we could give to the electrician, countertop people, etc, which simplified things quite a bit for us. (Cost: $350) We then chose the option of their sending someone over for a day to help with cabinet installation, which was tricky even for my DH who's worked with cabinets before. By the time he left, 80% of the cabinets were installed, and my DH felt comfortable knowing what he was doing. (Cost: $600 - both were money well spent.)
IKEA is easy to work with because everything is always available. No waiting weeks if you make a mistake with DIY. DH made a measuring mistake drilling the hardware spot on one, and simply went to IKEA the next day for a new drawerfront. (Cost: $35) By contrast, another friend is having her re-done also (by a cabinet company) and they've made mistakes a couple of times. She's had to wait several weeks each time for them to fix it so it's put the project on hold for two months,

and at one point none of them were speaking to eachother, lol.

(Our whole kitchen was done in 3 weeks.) She now hates her cabinets.
All I can say is do your research, and examine your own budget. If you have $30K to spend on cabinets, then IKEA might not be the way to go. But if you're on a budget (like we are) and want fresh, clean and innovative, then IKEA is definitely worth a look. We have a friend who works in the cabinet business who was really surprised at how nice ours were and how they had the same hardware as some of the more expensive cabinets.
If anyone has any ?s, I'd be happy to answer if I can.
