I've heard from my carpenter that buying unassembled or "RTA" kitchen cabinets can save you tremendous money. Does anyone know of any good manufacturers who will sell them unassembled?
The Home Depot actually carries unassembled kitchen cabinets. They may not keep them in stock and they may have to be special ordered, but they do have them on their website if you dig deep enough.
IKEA, IKEA, IKEA.
They have some really nice designs and are reasonably priced.
We renovated our kitchen with a full suite of their cabinets.
