Countertop samples to view?

Hello neighbors! I am thinking about replacing a countertop in my kitchen. I am currently favoring using a stone composite material, such as Corian. Does anyone know of anywhere (besides Home Depot) that has a nice selection of samples on site for viewing? Also, anyone have good or bad opinions on this material, and installers? We’d love to hear some feedback! Thank you, Tazio Hilbert Sent from my iPhone
