We implemented Timers into our code this year, and they are great. We set ours to fire off every millisecond. Unfortunately, we didn't have the time, but we plan to write a wrapper around one timer so we can schedule "events" to happen at certain time intervals. But so far, the timers have been proven to be extremely useful and you should definitely implement them.

Some tips, your interrupt routine should be fast. In fact, you should really only be really incrementing a number in it. Remember that since your timer is firing every X milliseconds, your number is being increased very rapidly. So use a big type like a long, or a long short. These will last your for days.

Also, always, always, always, disable your timer interrupts before trying to access your "tick" variable. Bad things will happen if you don't.
