We ordered our "boomerang" Formica from Home Depot. It was a 4' x 12' piece and cost us $150. This was last fall. They can special order any Formica or WilsonArt pattern. We ordered only the laminate and constructed the countertop ourselves. We also used it as the backsplash in kitchen area and for the shower wall. It worked great! We got the counter edging from Outwater Plastics online.
Interesting comments on the Formica site regarding the demand for the discontinued aqua boomerang. I can't afford the wilsonart laminate and can't find any old stock aqua boomerang so for now I'm settling for sanded birch plywood with Minwax applied. I'm rather surprised there are no companies producing cool retro designs.
