Digital BW, The Print

Hi again :)

So after researching what's available in terms of 13" printers, it
seems that a refurbished 1270 won't cost me much more than a used
1200, and the 1270 has OSX drivers, which is a plus. 

My only concern - I know that the 1270 uses the "chipped" cartridges
designed to prevent 3rd parties from making inks for it - has anyone
tried the MIS prefilled cartridges in this printer? I assume that they
wouldn't offer the cartridges if they didn't work, but before I buy a
system I want to make sure I'm getting something that will be reliable
for printing hextones. (I'm determined to use my 2000p for color work,
so the 1270 would be a dedicated BW printer)

Scouting prices on ebay it seems that 1200s and 1160s are pretty
pricey, perhaps because they're easier to use with CIS systems? Seems
to me that having a printer with up-to-date drivers would be an
advantage, especially since Photoshop 7 is going to be OSX native.
