How can I find out if a charger (i.e. one I already have) is a so-called
intelligent charger (i.e. one which monitors the batteries and starts
charging with a trickle current once they are nearly charged)?

Look inside it? If it appears to have electronics - like an IC - it's
likely to be reasonably intelligent. Basic ones - like supplied with some
cheap drills merely use a DC power supply and a series resistor.

And, are all intelligent chargers mostly equal, or is there some very
good reason for some of them selling for £10 and some selling for more
than four times that price?

Dunno. I stick to charging at the 1/10th capacity rate which takes
overnight. Batteries last a long time with this.
