Digital BW, The Print

I previously wrote about the 2200 not recognizing ink in the Black 
position.  Thanks to Charles Becker and Paul Roark for responding.

I purchased the 2200 not a year ago from the Epson Store as 
refurbished unit.  Luckily they agreed to replace it with a 
refurbished printer.  I finally got the refurbished printer 
yesterday, only it is an 1800--not a 2200.  I like the 2200 for its 
ability to print B&W using MIS UT7 inks on matte paper.  I've read 
that the 1800 does a good job with glossy paper but not such a good 
deal with matte paper using their matte black ink.

I have several OEM inks and MIS UT7 inks for the 2200.  I have also 
ordered a used 2200 from EBay; and as it has not used for about 3 
months, I am hoping that when it arrives in a few days, it is a good 
functioning printer.

Here are my questions:

1.  Did I get a good deal?  I am thinking that Epaon did not have any 
more refurbished 2200's to resupply me.

2.  As the 2400 is the upgrade for the 2200, should I ask them for 
this upgrade instead--even offering to chip in some ? money in the 
exchange?

3.  Should I just keep the 1800 and reserve it for colored glossies 
and use the 2200 with the MIS inks?

4.  If you think #2 is a good answer, do you think I should go for 
broke and try to get a deal on a 3800?

Well, it is the Christmas season, and I have many jobs ready to que 
up and print; so any help you can give me on sorting this out would 
be appreciated.

Thank you in advance.
