Q: Do acrylic shells cost more than wood shells?
A: Yes they do. Acrylic is a more expensive material than wood. Since wood shells are made of several plies of wood (technically speaking, that's plywood), we'll use plywood as a comparison. Go down to your local building supply and you'll find that 1/4" sheet of plywood is about $12, even really expensive veneered plywood is usually less than $50. Now get a price on the the same size sheet in 1/4" (6 mm) high grade cast acrylic, and you'll find it's well over $100 and often as much as $180.
