I have my wedding upcoming as well, and I was considering the same thing. I was going to give a starter set to each guy, and I think by buying the razors on ebay and honing and cleaning them myself, and then giving them a cheap brush/soap/strop, I could afford it, but after feeling it out for a bit, I'm positive none of them would truly enjoy it.

I think it's one of those things that you have to actively want to do yourself. The biggest problem they would have with it is how much longer it takes to shave. As soon as they hear it, they don't want to hear any more. They are way too content with their shaves already to wake up any earlier and fiddle with the straight. I'm sure they would try it a couple times, but they won't see the point. It's hard to see the point when you're content with what you have, I guess. If they weren't content, they would already be browsing the internet and finding this site just like I did.

But you know your friends better than I do of course, so if you're still going forward with it, I would say pick up an omega boar brush or a tweezerman brush for each of them for like $10-15, and some honeybee spa soap (~$3.50/puck), or something else inexpensive, and then something like the filly strop from ruprazor ($20). As far as the razors themselves, I can't help you much. As I said, I was going to restore my own from the bay, and I could have gotten away for less than $20/razor easy. So I was looking at kits that would be on the order of $50 per groomsman.

Good luck either way!
