Not least because that's the market price. See 'law of supply and demand' !
They'd need at least 100 factories turning this stuff out to reduce end user
pricing.

Must have been a voltage sensitive device. IIRC, NiCads will go 1.5V but
NiMH only 1.2....
I've had no probs at all so far; everything works beyond perfectly!

As I understand it, a NiMH charger can universally be used to charge
NiCd, but an NiCd charger only *might* be usable with NiMH. But then,
I've also been told that NiCd-powered cordless phones are universally
compatible with NiMH. I can't vouch for either statement, though, and
David's experience makes me doubt the latter.
For whatever that's worth....

I recently got a new high-speed NiMH charger which specifies that it is
ONLY to be used with NiMH, not NiCd.
