Digital BW, The Print

I'm looking to buy a printer for b&w digital printing and from the 
advice I've gotten and the posts I've read, Epson appears to be the 
printer of choice for the group with the 2400 being the preferred 
model. At this time my budget probably won't allow for the $500 refurb 
unit I saw on the Epson web site. My question is:

Does anyone have experience with the following Epson models in b&w 
printing?

R800

1200

1800

Also, if you have found a good, reliable place to buy one, please let 
me know. Any and all comments greatly appreciated.
