I'm in the market for some new blades myself, what is the TSR discount code please Jay?I can recommend gemstone trading & Connaught, excellent service from both.
They have their own e-commerce sites so you don't have to buy through eBay & offer a TSR discount if you go direct.
The Russian seller mentioned already for Rapira blades is the bees knees. I've bought from him a few times & very, very good. If he doesn't have exactly what you want send him a message. He will combine postage too.
