The other approach is to use breakout boards, e.g. the ones from Bellin 
Dynamic Systems (sold by Mouser).

They convert from various SMT packages to a DIP pattern, and work fine 
at low to moderate speed (< 100 MHz, say).

It's silly to use any of the above with MCUs.  Unless you are building a 
production run, why not just buy an MCU board and connect your circuit 
to it?  MCU boards often have a debugger interface and a reset button 
and other important features you won't have to bother with.  There is 
little need to reinvent the wheel for every project.

You might buy an MCU board with pins, plug it into your breadboard, and
then find there's a peripheral chip you want to use that's only
available in SMT.  So you want a breakout adapter for THAT.

This looks cool, a supposedly $5 board (in prototype now) in DIP20 (0.3
inch) format with an FRAM MSP430 processor and space for a RTC crystal
and external SRAM or FRAM:
