Digital BW, The Print

I am totally befuddled as to whether this printer is a good
'investment' or not: I have read numerous posts that GoodOnes are
great performers and reliable, but that the BadOnes have miserable
print banding and all attempts at repair will not heal their
ailments..... ???

Whats the story ?? 
 
(I have an excellent 2000P that works quite well for 8x10 and 12x16
prints, I would be using the 3000 only for 16x20 format)

Anyone have a GoodOne for sale ?

Thanks,
