[sdiy] Typical ESR of different capacitors

I'm doing a small digital board that uses an LDO for the +5V supply. This 
requires a capacitor with relatively low ESR and it got me thinking:

What is the range of typical ESR in various types of capacitors?

It's been hard / impossible to find good information online about the 
topic as manufacturers tend to only list ESR for their low-ESR capacitor 
models. However, if I pick random small value electrolytic, tantalum and 
ceramic capacitors, what ballpark can I expect the ESR to be in each
