your call :) but they need to remind the person you give them too of you, so copying the "classic" look is not a great plan imho. I use Claimid.com (there are others out there like about.me) as a "home" URL so that people can link up in a way that best suits them.
I would check out moo.com whatever you decide. Simple, low cost and classy looking (oh and the small ones stick out)
Couple of ideas;
- include your picture also the one you use as your avavtar on social media if it is different
- if you have some graphics skills make a set of cards for each event you attend
