creating a 50hz clock

I would like to create a 50hz ttl clock, but I am unsure of the best way to do it. I was thinking of using a 555 timer, but it can be difficult to get a 50% duty cyle using the 555 timers. I was then thinking about a crystal oscillator, but it looks like they are for much higher frequencies. Are there any other options, or do I just have to make due with the 555 timer? Thanks for any help.

How accurate are you looking for? In my analog electronics class this semester, a couple people built a 555 timer circuit. They got fairly poor accuracy using an RC circuit. Honestly, I got kinda lost on the oscillator chapter (and PSPICE is bad with oscillators) so I can't be of that much help.
 
I'm not really sure how accurate the design needs to be right now. I just know that it is difficult to build a 555 timer circuit that is precise. So I thought I would see if anyone knew of any other options. Thanks for the replies btw.
 
I've got a EE friend. Yea, he's currently working on a real time time machine for his senior design. We're currently establishing some sort of display that will provide news of what has happened in the world while a traveler is in the machine. We're going with a CNN style format.
