I have owned all three manufacturers printers. HP and Canon use different printing technology than Epson. The all produce great pictures. The Epson by far had the most clogs (although my experience was quite a few years ago). From reading other peoples viewpoints, some of the Epson printers are still clog happy while a few models seem to have improved significantly.
With HP and Canon, I have had great results with little clogging. I'm not a heavy user, so that speaks quite well for these machines since popular opinion indicates lack of use tends to increase the clogging. I'm not that familiar with 17" models, but you aren't far from 24" and you might want to consider that size especially if they have larger ink tanks and thus lower cost ink.
I think Canon and HP have rebates going right now. I'll be curious to hear what you decide to go with. Good luck.
