I recently reached a hobby milestone after about ten years of collecting: one thousand painted 40k models. Some of the early ones aren't painted terribly well (and some of the later ones too!) but I don't care. I painted a chaplain to celebrate.
edit: for info, you can find my current painting log here:
includes forces of the imperium, eldar, marines, daemons, tyranids, orks and Fabius Bile's New Men.
and my old logs here:
includes Tau pt.1, tyranids, marines and necrons
includes Tau pt.2
