I came across a great site which may or may not be of use to you if you thinking of remodelling your kitchen and doing it yourself and want to make your own kitchen cabinets but without all the cutting and waste.
If you do want to cut etc then their catalog is a huge plus it has all the combinations and sizes already made up so its easy to mix and match.
Saw them in Fine Woodworking advert
Here is the link
You have to sign up to be able to download the catalog but believe me its worth it with what it contains. I would not think of doing a kitchen without looking at these parts. By the way they did not seem that pricy when one considers waste cutting time and the price a hobbiest gets to by board at.
