RCA's have decent build quality generally, but they have the absolute WORST ergonomics, menu systems, and interfaces of any TV brand. They should in no way be considered a premium brand.
Sony makes the best TVs, with Toshiba, Mitsubishi, and Panasonic all being quality alternatives. Philips and Samsung are decent.
But know that virtually all sub-$1000 TVs are made with cheap components that are designed to last no more than 10 years. Since nearly all consumers shop based on price, all manufacturers have spec'ed lower quality components to reduce cost in order to stay competitive. And since TVs are becoming more and more high-tech, their life cycle is becoming shorter as new features are introduced more often.
Higher-end, more expensive TVs are built better, but may still be obsolete in 10 years as technology improves, and especially as content distribution bandwidth increases.
Just stuff to keep in mind.
