We replaced the main sail on our Tartan 27' this summer. We used sailwarehouse.com whose offices are in Monterey, CA and their sail loft is somewhere in Thailand. They came in about $1K cheaper then a local loft and we have been quite happy with the new sail.
They have a lot of 'stock' sails and list a 130% furling genoa for your boat (P26) at $1295.
The salesman on the phone was quite pleasant, knowledgeable and helpful.
You could find a used sail from a place like Minnie's: HEADSAILS - LUFF SIZE 26' TO 45'
but as Faster already suggested it is difficult to tell if a sail has been 'blown out' until you try it on your boat.
No affiliation with the sail warehouse, just a satisfied customer.
