Latest project was to replace the (non-original) formica countertop with a stainless one. Started with a commercial grade stainless kitchen prep table: http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1
Then had it waterjet cut to size and added a sink cutout.
Final product was installed over 3/4" plywood.
Bought them from Amazon, but like you said they are also available at Big Box stores. They come on a sheet but can be cut apart as needed. I attached them directly over the Zolatoned aluminum wall (visible in earlier Countertop pic).
