Epson has had discounts on the printer for months. The GS6000 (Solvent printer was discontinued from Epson about 3 months ago) and came out with 3 new solvent printers (64"). The 11880 won't be discontinued for a while (no rumors about it being discontinued yet).
The Canon IPF9400 is very close in quality, but speed may be a bit quicker with Canon. Both brands have done great quality and speed to be pretty comparable.
