When you are buying new cabinets, you have to decide if you want custom, semi-custom cabinets, or RTA kitchen 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 the custom made ones. Semi-custom cabinets almost always cost less.
