I would recommend getting an Epson WorkForce ET-4500 EcoTank these printers have the ink in a well on the outside. It costs about $399, and I know you are going to say you don't have the budget but think of this. You use Epson 79 inks and the page yield for standard ink is about 800 pages. Then to replace the full set of ink for $70. (I find it amazing that all my inks run out at the same time)
The ET-4500 will print 4,000 black & white and 6,500 color prints and this inks if you had to replace them all is $50.00 for the full set. You would have to replace the Epson 79 inks 8 times before you run out of ink in the ET-4500 that's a savings of almost $500 just on your first set of inks! and would have paid for the printer. I believe there is an other one that goes for $499 not sure what the difference is but now a days its cheaper to just buy a new printer when your inks run out but with the ET-4500 you would not have to do that.
Good luck.
