I've been searching, without luck, for an LTSpice compatible model for the CA3130, CA3140 and CA3240 op-amps. Can anyone point me in the right direction?

I'd be inclined to use a modern device for which a SPICE model is available.

You're probably right, I actually only want to compare performance with a couple of "modern" devices such as the LTC6241, without wasting extra time building circuits for the comparison. I have a heap of CA3130s in stock and would like to use them for my current, (single-supply), precision rectifier if it's feasible. In simulation, at least, I can't get better performance from newer op-amps than I expect from the 3130, especially regarding outputs going somewhere (real) close to 0V and speed, (if I'm careful about choice of compensation caps.) I need rail-to-rail inputs and outputs, with the ability to handle inputs that go down to 400mV below the negative rail in a single-supply circuit. (I'm not asking for much - just perfection and a bit of magic.)
