I have now bought router bits a few times from these lovely people - I believe they used to run Oregon Carbide Saw sharpening and have a good selection of unused Whiteside router bits. If you call with the bit number you are looking for they'll let you know if they have it or not. Also willing to let you pick through the bags of bits.
Prices have generally been >50% off of retail for unused bits - pretty stellar deals if you ask me.
Give Tad a call at 503.936.3804 and tell him you're from the Guild. Happy shopping!
