Are Pierco 1 - piece frames the way to go? As I threw out my 1996 catalogs, I can't confirm the prices, but as I recall, a new wood medium frame with plastic foundation was more expensive than a new all-plastic medium frame (I only use mediums). Add to that your assembly time for the wood frame and potential for wax moth damage, and I contend the all-plastic frame wins the cost analysis hands down. W. G. Miller Gaithersburg, MD
