Thanks again
LTspice or any spice is VERY good for the use you want it for. You can build a regulator, experiment with current values, 'what if' questions, that sort of thing.
For instance, you can verify how the ripple rejection changes when you vary the series resistance to the zener. That is ideal to play with your circuit before putting it in hardware.
You don't get a 0.0001% correct value answer, but almost always you get a correct 'trend' answer, and that's very important.
Also in hardware you wouldn't get 0.0001% correct values.

And let's face it, it is totally irrelevant whether your opamp supply gives out 14.8 or 15.123 or something in that area. 15V supply is just a design value.
