You're welcome!
Amplifier design is much trickier, but easy to accomplish when you start to understand all the different variables involved.
These days, with the ubiquity of the op-amp, it's almost a lost art.
I still love designing wide-band amplifier front ends for ADC's using discrete parts, but you can get anything you need with very wide bandwidths in op amps now. It's not worth the trouble anymore, especially if time to market is a deciding factor.
I do it only to keep my head from going rusty, but in a final design I will almost always use op-amps, as much as I can.
