I'll second Andy's recommendation for Canon, Shades of Paper and Jason... The Canon printers are not talked about nearly enough, but they're great machines - much lower maintenance than the Epsons, and very nice image quality. Of course, I haven't seen a print sample from the 6300/8300 line yet, but the 6100 has a gamut somewhat larger in most areas than an Epson 7880, approaching the 7900 in some selected (cool) tones. If the 6300/8300 line is really 20% larger gamut, they'll exceed the 7900's gamut just about everywhere. Canon's ink usage is lower than Epson's (less cleaning), which goes a long way towards dealing with the more expensive inks on the 24-inch models - I suspect they are actually about the same price per print, if not cheaper than Epson. The 44 inch models use the 330 and 700 ml ink tanks, which gets the price per ml down, as well as probably never running out of ink (with Canon's ink economy plus those big cartridges, I would imagine that the number of prints per cartridge is staggeringly high)! My 6100 gets about six rolls of 24-inchx39 foot paper from the cartridge that runs out the most often (one of the grays - all the neutrals drain quickly), and well over twice that from the slower draining cartridges (12 rolls after installation, there are still a couple of starter cartridges in the machine, and only a couple of neutrals have gone through a starter plus the first full cartridge and been replaced twice. With 330 ml cartridges in the 44 inch machine, nearly triple that, so the fast-draining cartridges will go through one cartridge for 15-16 rolls of 24-inch paper (8-10 rolls of 44 inch), and the slow cartridges will last forever...
