Digital BW, The Print

Hi, 

I've been printing Black Only with an Epson r265 and am delighted with
the quality.  I've been using Epson black ink cartridges but I've
decided I want to make lots of prints, so I'm looking for a refillable
solution.  There are lots of websites around that sell refillable
cartridges e.g.

http://www.laserdesigns.co.uk/ldcm_refillable_ink_cartridges_info.html

and lots of places that sell ink e.g.

http://www.fotospeed.com/Fotospeed-Universal-Crystal-Dye-(Epson)/products/2461/

Can anyone advise me on which to buy?  I have seen a lot of
recommendations for Eboni ink, but looking at the inksupply.com
website I don't think they have cartridges for the r265.  Can I just
buy the Eboni ink and put it in a different cartridge?  I have heard
that there may be problems running pigment ink in the r265 since it
was designed for dye ink - is that true?  I am tempted by the products
on cityinkexpress - either the dye refill kit

or the pigment one

Would either of these give results of similar quality to the original
Epsom cartridges?  I'm quite happy to play about with different
profile settings, as long as I can get a good result in the end!

Thanks for any advice.
