Never found it hard to build an oscillator, the hard part is musical voltage per octave. 3340 repro chips are the way to go, the best non-3340 circuit I've seen is this one and it's still temperature-sensitive: https://www.youtube.com/watch?v=FiCMjt0mqvI

3340s are great. I've also heard good things about the SSI2130 and 2131 chips as a more modern alternative to 3340.

3340s are more DIY-friendly though, as they're DIP packages.
