I have a Cateye Astrale 8. It does all of the standard functions plus cadance. On a friends recommdation I switched to it so I would know my cadance. As a new rider the cadance was very helpful and still is. Like everyone says here, keep it above 90. One odd thing I noticed is that when I switched bikes and put the old computer on the new bike I seem to be at the same comfort level at a higher cadance. On the old bike I stayed between 90-95 and on the new one I look down and will be at 98-100. I don't know if the bike is smoother or it is because it fits me better. It has a little bit different frame dimensions. Of course it could all be in my head.
