The hp 9XX series is great! I got the 970cxi myself, and got it for nearly two years ago (a few days after it came on the market). It have been replaced by the 960, 980 and 990. All are great printers. Superb print quality, fast, quiet, low ink use (low print costs).
The new canon printers are also supposed to be fine. And the photo epsons have great print quality. Although higher print costs, and more prone to failure.
For scanners I really like canon's budget scanners, I used a few different models, with the 650, 656, 1220 etc. Although you are in the market for higher end scanners. But for most the cheap canon scanners would be great, and would perform almost as good as the more expencive ones. (allittle weaker color balance, perhaps less dpi's, slower and a cheaper look)
