Which chips to look at?   I've used a 4046 but it looks like there is
something better with a digital interface that works a higher frequency.
 What is the easiest to use and with affordable prices.

   BTW While working with a bare PIC requires some hard to acquire skills,
new uP platforms like Arduino make software easy for just about anyone.
