Perhaps you'd entertain a non-Wien Bridge oscillator: MFB_Oscillator. A working example sine wave oscillator schematic using an MFB (multiple feedback) topology. It uses no more parts than the usual Wien bridge and offers significantly better (distortion) performance.

I got a LTspice model working well, using a diode and filter feedback to adjust a behavioral resistor, but that¡¯s cheating.
