Have had a little experience with Ikea kitchens, what has been said before (you get what you pay for) is correct. The drawers and hinges are Blum but made for Ikea so are the lowest quality, the MDF board is the same not as dense and thinner coating than normal MDF. Having said that the price of kitchens here is over the top.
If you are getting Ikea quotes of 25k it must be big.
What I would do is go with an Ikea kitchen without the benchtops (if you are looking at laminate tops) and appliances, make sure you get the soft close runners for drawers. Get a local guy to make the tops and look for a deal on appliances (Jan sales almost here!!) we bought some appliances from Seipp in Germany on sale quite cheap.
Assembly is the critical thing with these things to get them to last, insist your installer glues every joint and dowel. A dob of silicon on the back of all drawer runners and hinges will help hold them in the dodgy MDF they use.
