Digital BW, The Print

Hi.

I've been reading the 'refillable 2400 cart' thread... I'm looking
for some help to find out how I can keep using 3MK with my r1800..

I've been looking at a few options, mainly spongeless carts..

Should I steer clear of the cartridges that are/can be refilled in 
the printer? (I see there are two types; filling  just with a needle, 
and filling with vacuum method (seems to have problems with leaking)
And what are the issues with refilling carts if they're half full, 
while they're still in the printer?

Could I use an empty CIS system and fill using just three spots with
Eboni? Perhaps using cleaning solution in the remaning positions, or 
just oem carts? ...I'm concerned with quality, so what should I expect 
to pay for this? 


Any suggestions would be great, as it seems MIS just now stopped 
selling most spongeless empty, and prefilled carts.


thanks for any help
