re Refilling HP laser cartridges

No. haven't (quite) done it yet, but -

Long annoyed by the manifest profiteering of both the new and after market
laser printer cartridge market  I took time out to attack an HP toner
cartridge.

Have toner everywhere :-)
Have now opened a cartridge and know where the main toner reservoir is.
Know where the filling bung is - perfectly obvious and visible in
retrospect.
Know where one can safely and reasonably drill large holes for refilling if
one considers the bung hard to get to (which it is).

A would be refilled-cartridge-seller assures me the toner is carcinogenic.
Who knows.
One suspects this is a desperate sales ploy, but ... (Anyone know?)
I imagine it is not appreciably more so than other toners which ARE
available in bulk/loose form.

Next step, lets see what damage I can do to a printer with toner from other
sources.
(HP refills are apparently about as available to the retail market as
CocaCola mix-at-point-of-sale drink machine concentrate (and may taste about
as good :-))
One source which commends itself is large HP refills for up market HP
printers which work out MUCH cheaper per copy.

Anyone else's comments on any part of this process would be useful.
Can you do it?
Have YOU done it?
What toner suits?

I'm playing with an (old) EPP cartridge but the lessons should apply to
other models.
I know that some toners definitely make a large sticky mess in some other
systems. What works in which HP?
