Probably stating the obvious, but National Sail Supply sells sails made by the Rolly Tasker loft in Thailand. I have ordered a main sail from them--about 10 years ago for a different boat--and was quite happy with the quality.
I recently went through the process of replacing a furling headsail and went through my local loft. With my knowledge, and their recommendation, they outsourced it to the Durtek loft (Quantum owned) in Sri Lanka. I purchased a tri-radial cut genoa using Marblehead cloth and a silver Sunbrella UV cover for a very good price. My local sailmaker measured for, and inspected it, and helped bend it on when it arrived. Very, very happy with the purchase. This was after I received a quote from National which did not offer a tri-radial option, but gave me a quote for a cross-cut furling genoa. I also got quotes from other lofts including Precision, another local loft, and considered the Catalina Direct (Ullman) sails. I seriously considered going with National Sail again. Dirk has always been extremely responsive to any inquiries.
National will inspect the sail before shipping it on to you. But any follow-up is via email and (potentially) remote repairs/alterations. In my case I can always go to the local sailmaker I trust for any issues related to the sail. Something to think about.
The only thing I didn't like about the mainsail that I purchased from National (loose footed, 2 partial, 2 full battens) was the clew attachment. They utilized a velcro strap which I found would bind when adjusting the outhaul. I prefer a slug to ride in the boom slot.
Hope this helps.
