Ideal analog switch to replace BJT / MOSFET in the modern world
No switch is perfect. Switch selection is based on the load that you are going to handle. No load has zero inductance or zero capacitance. Hence there will be surges and kick backs. It should be handled right - if not the circuit will fail under certain inputs. 

Now-a-days you could easily find FETs with very low RDS ON (even 2.0 milli Ohms is not uncommon. Typically automotive industry pays pittance for those parts - but open market pricing could be expensive. I have never tried get those outside, but I guess even if it is triple it is still within your target). But once the RDS on is low, if you ever drive it in linear mode, it could easily smoke.
