Cheers Lads. Bought 200 Astra's from bigdealsmart. Great price and most importantly free postage. I used to hate Astra's but I have grown to appreciate their smoothness. They are great in my Tatara Nodachi. Should last me a good while.
Depends on the blade you want. For Gem and AC - Connaught, for regular blades both DE and SE - La Barbiera (free postage) and for blades not available there - razorbladesclub (Germany). At the time of writing razorbladesclub does Feather AC blades in singles so good to build an AC sample pack.
