True...  The SX28 protoboard has the same form factor.  It also has the same PRICE!

The choice between the two protoboards should obviosuly be based upon the device that will be used in the final project.  Yet sometimes the protoboard itself can be the final project!  Since the SX48 offers twice the program memory of the SX28 in additon to more internal RAM and more I/O pins it seems like an obvious choice for ANY project that can be completed on the protoboard itself.

Bennettdan, if you can complete your project on a protoboard, I recommend going with the SX48 if only because it has more memory than the SX28 for the same price.  To me, the only real advantage the SX28 has over the SX48 is that the DIP packaging of the chip is much easier to work with as hobbiests.

I hope that helps.
