First things first: learn how to shave with a straight razor, and find out if it's for you.
If it is, there a high chance (maybe I'd better write "risk":w) that straight razor shaving becomes a hobby. I would have never believed that, before I started doing it myself.
When and if the shaving bug bites, things will look different. And it won't be cheap.:cry:
For now, just buy a shaveready razor and a decent strop. If you make your homework and read the Wiki entries about stropping and shaving, you'll be able to shave several weeks to months before the razor needs additional care. At that point $5 spent on Chromium Oxide and a homemade paddle strop is all it takes to tune up the edge.
By the time you'll need more than that, you'll have a completely other perspective on straight razor shaving.
