Others more knowledgeable than myself may offer a better suggestion, but I believe if you power the 74HC595 with a 3.3V power supply, it will work fine as a shift register for the Pi. I have not actually tried this, but a quick google shows them being used quite a bit on the Pi. I haven't actually hooked mine up to a shift register yet so I don't speak from personal experience though.
The 74HC595 in a DIP package is easy to find.
