The PDIP package is what you want, not the SOIC. The only difference is 
size. DIP packages are human-friendly, surface mount is for robots.

I have it in a breadboard right now, to make it more permanent I would 
solder a socket to a prototyping board then (after verifying the 
connections) plug the chip into the socket. Soldering to the pins makes 
it difficult to replace the IC, and risks damaging it with the heat if 
you're not good at soldering quickly and to the point. A CD4051 would 
also work, it's basically the same circuit.
