Hi Mike, I know it can be quite daunting knowing what is and is not a good printer. Especially when you want to know that you are buyig the best for 1400 dollars, I had to convert that to euros for me and it is €1000. Look, I can only share with you my technique for sampling through the information.
Prioritise your needs. I bought a printer based mainly upon its ability to handle different media, in your case Canvas. Search in google for terms such as Canvas printing and epson printer or canon or HP. Reviews on Canon printer and canvas printing. Get reviews from Google.
My personal opinion? I started with canon and when that went wonky moved straight to Epson. Why, simply because of Media and more importantly I have noticed that practically all paper manufacturers and special media suppliers provide ICC profiles and specs for their particular paper with Epson printers. I have sometimes noticed Canon missing or more frequently even HP missing in the ICC profile lists and manufacturers support of their own branded media.
I am in no position to offer pointers, my experience is that Epson is a good and reliable brand, all the important third party papers are supported and even Black and White profiles for the advanced black and white mode has ICC profiles for it. And the ink costs from the 3800 upwards are good, not desirable , still a rip off, but in comparison to specs I have read with other printers they are good. Epson's support in Europe is, from the few times that I have contacted them, less than knowledgeable - I get all my info from users, the technical support is quite irritating from untrained staff. But is it any different from canon or HP?
For a quick and very reliable overview about the Epson 3800 (you really do not want to go lower if you are going to print fairly regularly and canvas is an ink eater, so deffinately not below a 3800) go to http://people.csail.mit.edu/ericchan/
Hope this helps you. I also hope that people with canons might give you feedback as well.
