The cheapest is a 74HC90 with a 74HC14 one as input the other  five as
output. Can also be LS.
The best with all bells and whistles is a Altera MAX  3000 gate array with
two selectable outputs paralleling four outputs with  resisters,
transformer input with Wenzel    and sync input. No  SMD's very solderable but needs a
PCB and its cost is volume dependant. $ 6 if  40 get ordered and the rest
of the parts less than $ 9.
There is also room to bring out all decade stages    5/10 MHz input select
and 80/20 or 50/50 duty  cycle.
