All-In-One Mini Q-Control Unit

Why not design a board with the MAX chips integrated into it. This would allow for a much smaller footprint, and also allow for an OMEGA style connector for the thermocouples. 

Then I priced the chips on Mouser and Digikey, and was quite disappointed to find they are quite pricey. Almost $13 a chip. It would be much cheaper to re-purpose the chips from the chinese boards from places like e-bay and such. Just an option.

I'd like to start designing a board with both options maybe. 1 with plug-in style, and 1 with on-board option, or maybe these two options could be incorporated into the same board. 

Do you have a schematic of how all this gets hooked up? 

Cheers,

So why use the max6675 when the max31855 is an updated version and more readily available?  On Mouser the newer chip is ~$4.  

And +1 for Omega connector style
