I too just switched to a 4800 and I love it! It is considerably more expensive then a 1280 but with all the ink I flushed down the 'tube' on print head clogs i think it will be well worth it. I don't have a clue how this 'monster' could be brought on the road but my bach aches just thinking about it. I personally unloaded it from the crate and onto my desk but everyone recommends using two people. (right Chuck?) Anway, the features and the incredible job (and speed) that it prints at is just incredible. I had pretty much allways used roll paper on my 1280 but was a bit of a pain cutting off the individual sheets from the 1280. I ended up put a 1" wide piece of gold tape from JDS where the paper feeds to on the output tray without removing the top layer of protective paper on it for a smooth cutting surface.
The automatic cut off features is wonderul. I especially like that unlike the 1280 with black and magenta being the primary colors that like to clog that the 4800 has one black cartridge, a light black cartridge and a light light black cartridge so that hopefully there will be less chance for clogging when utilizing those last 2 carts.
Good luck on your decision.
