I've shopped for Swanstone as an alternative to Corian about 6 months ago. I live in SE PA and the cheapest I could get it made (not installed) was for $85 per linear foot from a Fabricator. (The Dealers were, of course, a middle-mand and it cost more.) I had 42 linear feet and my wife didn't want to spend that kind of $$$.
The price didn't include making the template or the installation. Make sure you get 1/2" thickness or better. The 1/4" stuff is useless! My best to ya and hope this helps.
