We buy HP printers. There are good Canons and Epsons out there, but DH and I have been computer nerds for a long time, and both of us have consistantly been happier with HPs. The main problem with them is that the ink isn't quite as cheap as it can be with a Canon. On the Canons, there are 3 different colored cartridges and one black. When you run out of one color, you replace that one color. When you run out of yellow on an HP, you replace the whole colored cartridge since there are only 2 cartridges. The cost of 3 colored Canon cartridges is generally higher than 1 colored HP cartridge, but over time you'll get your money's worth with the Canons.
As long as you buy a name brand (I'd stick to Canon or HP), you probably won't be disappointed. There may be some aspects of the other brand that you'd have liked better, but you'll have a good printer that will probably last longer than you'll need it to. If you can, I'd spend as close to $200 as you can. Right now, that seems where the most value seems to be, provided that you don't really <i>need</i> one of the more expensive printers.
I'd also recommend making sure that you get a photo printer. Even if you don't have a digital camera yet, you probably will. Printers that aren't photo printers will print photos, but there are advantages to the photo printers. My favorite is being able to use 4X6 photo paper and printing to the edge on it. With a non-photo printer, you'll generally have to print on a full sheet of photo paper and trim the individual photos.
