If you want a true photo printer (up to 13x19) I'd say look for someone selling off a bundled Pro-100, or similar. You can pick one up for about the cost of the ink. ~$100, give or take a few bucks. The Pixma Pro series all use individual ink tanks, and I've found their inks aren't generally available at department stores, but are usually available at office supply stores (but much more expensive than buying online) just in case you run out and need more quick. They are also rather large and heavy, so you have to have the space to put one.
As far as dye vs pigment based inks, that depends on what you're printing. I've found that for color prints dye works great, but if you want to print black and white images, a pigment based printer is much better IMO. I've got an older dye-based Canon Pixma Pro 9000 Mark II as well as a newer pigment-based Pixma Pro-10, and I can tell a big difference in a monochrome image printed on the two printers. Don't get me wrong, the print looks good from the 9000 Mk II, until you look at the Pro-10 and it's great. Color images are great from both. The newer dye-based Pro-100 is probably better than the 9000 Mk II in this regard since I think they changed a few of the inks around. There is some debate on the longevity of dye vs pigment based inks, but I think either of them are sufficient for the average person printing photos. (The Pro-100 and older Pro-9000 Mk II printers are dye based and the Pro 9500 Mk II, Pro-10, and Pro-1 are pigment based printers.)
You may have already dabbled in color management since you've printed some before, but I'd highly suggest calibrating your monitor and making sure to use appropriate paper profiles when printing. It doesn't take that long, and really does make a big difference in the final print. If you don't want to buy a colorimeter to calibrate your monitor, you can always rent one from Lensrentals, or somewhere like that for a small percentage of the cost to buy one. It always amazes me when I see people with thousands of dollars in camera gear who cheap out on something as simple as color calibration.
