That's the attitude, go for it and before you know it you will be getting excellent shaves. For a first razor I recommend 6/8, grind anywhere from full hollow to 3/4, save the wedges for later.
I am very happy with this XY Gold Dollar razor I got off of eBay. I got it for $10.99 with free shipping, and it came with a leather case. See it here.
It really was. I was just looking for a pouch for one of my straights and ran across the GD 208. For the price I thought I'd give it a try. It supposedly honed by a honemeister, and I found it to be both sharp and smooth. YMMV
