Digital BW, The Print

Well, I had been all set to go with ordering the UT7 system on an 
Epson 2200 that I'm going to dedicate to B&W only.  However, I was 
picking up the printer from the refurbishing place and the tech said 
to use Piezography system and that it was the best and most 
troublefree system for the printer and for use on an Epson 2200. 
<BTW, he doesn't sell them.> He also recommended a cartridge system 
over a CIS - saying that the CIS was likely to give me problems.  
This feels like a case where the more I hear, the more confused I 
get.

Anyway, I am going to dedicate the refurbished printer to B&W.  Is 
the UT7 system better or is the Piezography system better?  I am 
planning on trying it out using cartridges but the longer term 
intention is to go with a CIS if I like it. Reliable operation of 
the printer is very important to me.

If it matters, I'm using Windows XP.  I currently use Imageprint on 
what will remain my color printer.  The only thing to add is that 
I'm dedicating the second printer to B&W primarily to lower my 
printing costs.  

Any advice would be welcome and once I have a consensus here, I'm 
going to immediately order it before I get any more advice that will 
confuse me even more!  :-)

Thanks for any help.
