Well Gentleman I need a little assistance, I am currently shaving with a Pyramid but would like to start acquiring other blades. What brands should I look for when perusing Ebay?

I preferably would pay less than $50, I'm hoping I can hunt around and find good blades at cheap prices because they need work. I can then, anytime I want, just grab a razor and send it off to be restored. The end result being that I would have a nice arsenal of razors while not paying too much at any give one time for said stash of straights. As well as be able to shave with different blades, and figure out what I like shaving with the best.

Thank you in advance for your input, this newbie truly appreciates it!!!!
