  I'll see what I can find.   $20 oisn't bad, though.  Keep in mind that 
your boards become more complex and more expensive, and your reliabilty 
goes down with every additional chip you use.  So, is $20 really allthat 
expensive?  You'd be replacing 6 8 pin DIPS with an 8 pin DIP and a 16 
(24?) pin DIP.  Much simpler to fabricate, less expensive and smaller 
PCB,. 

   Now, if this is a one-off project, many of these issues will be 
irrelevant, but if you're planning to produce these boards for sale, the 
size and cost of the PCB is going to become MUCH more relevant to you.
