i used the figure 3 ckt in my lab for a test and the result was great.... a pure sine wave of abt 229KHz with abt 15Vpp....

In the Circuitmaker version "osc.ckt", you did not have power supplied to the opamp.

The +V gets connected to the top pin, the -v to the bottom pin.
I suggest +10v and -10v.

May I ask, what improvement do the extra parts in fig. 4 provide?
They gently clamp the max output swing of the opamp so that its output does not slam into the power supply rails and produce a badly clipped sine-wave like the first circuit does.
