When you are buying new kitchen cabinets you have to decide if you want custom/semi-custom cabinets, or RTA cabinets. There are reasons to go with any of these three options but RTA cabinets are usually the best choice. Custom and semi-custom cabinets are thought of as the high end cabinets. They tend to offer quality products with a lot of variety for a premium price. As their names should imply, Custom cabinets allow for a lot of customization while semi-custom cabinets allow a lot of change but not as much as custom. Semi-custom cabinets almost always cost less.
