What's the best cutting disc that you ever used in your works? Can anybody give me a tip on this. I'm short on cash and I'm looking for a cheap cutting disc that is durable for its price. I've seen some like this Smith & ARROW on ebay (http://stores.shop.ebay.com/smith-and-arrow__W0QQ_armrsZ1). They claim that they have a 100% positive feedback on all 6000 sales but I need more comments from you guys. Holler at me! Thanks
