I have, and had a great experience but can't remember who exactly it was (its been years). There are lots of suppliers out there with varying reputations. My advise would be to google for one reasonably close to you and then search here for comments on that supplier. In the alternative, you could ask for specific recommendations once you have the name of some local suppliers. My advice would be one that sends or posts pictures of the ACTUAL BOARD that you will be recieving. Other than that, there some element of caveat emptor, but unless you're buying a 10x4 foot slab of waterfall bubinga, your financial exposure shouldn't be all that much.
