looking for high quality opamp (half a watt input to opamp {inverting-amp @low impedance} up to 5mhz @unity) with low noise. Advice and/or experience with brand/model# and online outlet for purchase of single quantity. Thanks!!!!!!

What does "half a watt input" mean? Do you want the op-amp to eat half watt of power through its input terminals with low input impedance?
If its that, then you are searching for some super-natural op-amp and I guess you won't get one.

If you are searching for power amplifiers then there are many of them but for audio or probably super-sonic frequency. Not for HF/VHF range.
