Another way would be to get a P400, which doesn't need modification for refillable cartridges. It's only 13", but so was the 2200. Or an R1430, if you only print on matte.
However it's not clear that the OP wants to use a third party inkset. The comment about printing from LR suggests that he is using OEM inks and if so would be using one of the QTR-UC curves for B&W. In which case there are a range of recent Epsons that he could use with QTR, including a unmodified P800. I don't think that his legacy driver problems, if that is the problem, are a reason to avoid Epson.

As older Epson printers fail one method to use Piezography in the future will be to modify the Epson printer P800 so that one can continue to use QTR and the Cone inks. The obvious problem is that modifying the P800 is quite expensive and moreover the warranty is immediately voided.
