I'd recommend using web fonts if you desire layout consistency and complete control over the fonts rendered for your site. Here are some web font services to check out:
WebINK - No longer offered- Google Web Fonts
- TypeKit
- Fonts.com
All of these services provide thousands of high-quality fonts. Google fonts are totally free. WebINK and TypeKit both require a subscription model. I've never used fonts.com but they probably have a similar model.
