I've found the best prices on ebay. You may have to shop for a couple weeks waiting for the right deal to come along, but if you see a good price for a pan for a 351W, check the seller's "other items" and they sometimes have good prices on their other pans also. Some also offer free shipping, which will save you $20-40 dollars, depending on what some sellers charge for S&H.
