Another vote for dridiot. He da man! You can save two bucks if you opt for the two hundred blade pack. Won't need to re-order for a while. Great blades, fantastic seller. No way to go wrong.
ntguy, dridiot, or aynerisum over on the Vendor Thread.
Shoot them a PM and they'll give you a better price than what they sell them on ebay for because they can avoid the ebay fees.
I've bought blades from all of them. Think I just got 50 Feathers for $15 from one of them. You can get them cheaper in bigger quantities. They are all Singapore based vendors so it takes about 10 days to get your blades.
