I did not look to closely but are they all CMYK? All over shirt/textile production probably a good buy. For Chromaluxe production no need to spend that kind of money. looks like the CMYK 64" 300 model is around $6500.
My Epson P8000 44" dye sub conversion was $3195, plus carts and ink. 10 color too. If you only need 24" than the new Epson F570 would be perfect, $2495 includes 2 sets of ink and 300' of paper.
