Tom Van Baak published a list of PIC counters that give various ratios, 
such as 1e7 (10MHz to 1Hz) with jitter under 2ps. Here is a list with 
source code:

picDIV -- Single Chip Frequency Divider 
http://www.leapsecond.com/pic/picdiv.htm

PIC divider jitter measurement
http://www.leapsecond.com/pic/jitter/		

He also posted a different version to time events:

picPET -- Precision Event Timer, more versions

Sure, using Mircochip PICs much is possible
here my frequency counter in an RS232 connector, powered from the RS232 DTR::

But then he needs a PIC programmer etc...

I am sure an ebay search will get you many cheap frequency counters too.
