If you're interested in a free, but carefully hinted coding font, my Luculent font [0][1] may be worth a look. The hinting is its defining feature, since I hate fuzzy font rendering. I wrote every line of TTF hinting code in it myself (no autohinting), and it is legible down to 5x11 pixel sized characters even if you disable antialiasing, so long as your font engine interprets the hints.
