Centric is the most popular manufacturer of coated rotor (hats and edges). Just remember these are E-coated which is not as durable as powder coating or paint. It will eventually fade, wear, and rust like any other rotor. But they are, nevertheless, a well made rotor for the price. Other good (non coated) solid rotors include Brembo and the mentioned NAPA premiums.
You are justified in not wanting slotted or especially drilled rotors. Slotted rotors have a place on the track but that's about it. The drilled rotors you see on an occasional Porsche, Benz, etc. bear little resemblance to the ones commonly sold online. Their primary function is to minimize water vapor forming under the huge calipers those cars often have. They have small "cast" in holes that are chamfered and are made of premium (high carbon content) metals. They will still spider web (structural heat induced cracks) and can cost a small fortune to replace. Both drilled and or slotted rotors will also accelerate pad wear. The primary function of a slotted rotor is to scape the rotor surface of any glazing that might occur from overheating. The easiest way to solve this problem is to use a pad with friction material of the proper heat range for the intended use.
