Digital BW, The Print

So, there's this Epson 3000 up for sale locally (but, to 
paraphrase Woody Gutherie, I'm not saying which locality).  
According to the owner, it's seen some miles.  The heads likely 
need cleaning.  A few of the feed tubes to the print head could 
likely use replacement.  But it likely has an ethernet card in it 
already (a fairly big deal if confirmed).  And, it's cheap. _Really_ 
cheap.

I'll likely check it out tomorrow.  I may, in fact, have enough
pocket  money to pick it up and call a car service to drag it home 
if I'm feeling lucky.  The thing is, I've rarely dealt with any Epson 
larger than 13", and this would be the first I've ever owned.  I 
know the specs (the owner warned me about the limitations of 
four-color printers for "critical" color photo work, and was quite 
intrigued when I told him I wanted it for quad work).  What I want 
to know is: what should I be looking out for with a beastie like 
this?  In a worst-case scenario, what's the average tab for head 
replacement, should it come to that?  Given how cheap I'd be 
getting it for, I can deal with sinking a few hundred more in the 
thing to get it "right" if necessary (cheap compared to, say, laying 
out for a 4000), but I'd like the lay of the land regarding rollers, 
feed mechanisms, etc.  I've had great luck with my 1160, which I 
bought used (and keep on a steady diet of Lyson Quad Black 
Neutral), and this would be a chance to go bigger for relatively 
cheap.
