I really like the PIH design. 

Based on the board size, what would the cost be?

Bare boards, 10 or $24.90 from iteadstudio plus shipping, typically $5 to Boston, MA area.
So if I order 10, then $4 mailed in an envelope to you.
Materials: '1284s are $5.82 at Mouser, $4.50 for the FTDI chip, regulators ~75 cents?, USB connector ~$1, and whatever you can scrounge up for sockets/headers, Rs, Cs, LEDs.
Maybe ditch the surface mount parts and just put holes for pins for one of these one instead
http://www.mouser.com/ProductDetail/mikroElektronika/MIKROE-483/?qs=sGAEpiMZZMuNcqZxhMNT3znYT0k8AsjH
That'd be worth $5 saved in surface mounting aggravation to me! The same holes could allow an FTDI Basic to be jumpered in for programming and not be installed if the end application didn't need it, like a big Pro Mini.

Can get the rest pretty inexpensively from www.dipmicro.com
Think I'll add 3 more holes to allow for 3.3V from the FTDI if the 3.3V regulator is not used, and change the 5V regulator to a 7805 type.

JoeO,
Saw your PM attempt - system does not seem to be working yet.
Or I need to make some undetermined change still to allow PMs to work again.
Or my PMs are hosed as  a moderator.
Or ...
Either way, what's up?

Bob:

1284 Duelaminove PIH.  I would take up to 10 boards.  Would you want to have the whole panel sent to me  from the manufacturer and I would pay you the $40?

Boards coming from China. Customs, etc. Easier to receive & forward.

Grr,  I think I need to re-do the layout on the all-thru hole board. Eagle saying the schematic & layout are not compatible, every thing I try & fix just makes it worse. Not sure how they got that way, but it seems hopeless.

Okay, I had to re-do my .brd file, didn't seem to be anyway to recover.
Here's the new layout

and the files. Could use some feedback re: pin header labels - can't really squeeze things into the middle, the '644 placement is fixed by the ICSP header.
I suppose one way is make the board taller, slide everything up a tenth or so and out the labels around the outside.
Am using this neat little FTDI module vs the FTDI chip itself - figure the cost of the module and its parts is comparable to the chip, USB connector, some caps, and the hassle if soldering that chip in place!

Got some ordered to try out.
If anyone's up for a review, here are the eagle 6 files.

I took a peek at the layout
very neat

I think there’s space to add pin labels outside the pins
I find that easier especially once a shield is in place

I made it a little wider, cleaned up the right angle traces, added header pin names.
Think the names are too big this way?
[edit- fixed couple typos in the link]

I took the liberty of "adjusting" your link!

but it looks fine to me certainly not too big
but then my eyes[ancient] appreciate larger fonts!

you might try labels that run the other way
so rather than one label per pin you have one loooooooooooong label
A7  A6  A5  A4 etc

I tried horizontal labels, they're ok for 2 characters, 3 run into each other too much.
