IMHO, Site Meter is *the* best webcounter service out there right now. It's free, easy to use, stable, and provides a wealth of information on visitors. Since my site got listed in Schneier's "Crypto-Gram" newsletter yesterday, I've been using sitemeter to see who's visiting my site, from where, and what they clicked on to get to my site. All as a free service. It's awesome. :)

BTW, I've gotten over 2000 unique visitors to http://elonka.com/steganography since yesterday. Whee!
