I also use a straight razor, so it's a little more important. And much cheaper than good disposable blades. Between shave soap, new blades, (It's a cheap modern handle that takes them) and aftershave, I figure I spend about $10/year on shaveing and related supplies, not counting water usage, as that's included in my rent. Cost to get started (Handle, brush, mug) was less than $20.
I bought a 100 of double edge blades for $7.... It lasts for me more than year.
