There are a lot of factors that go into this, you can get cheap cabinets or more expensive; stock or custom or semi-custom; different types of wood and many other considerations. We used Enterprise Cabinets on 18th Avenue in BP. For custom maple cabinets we were very happy, particularly after pricing around with other "heimish" places.
Also, you need to consider the cost of installing the cabinets and who will be doing the installation. Most places have their guy, but may be expensive. See if your contractor does it.
