The Prusa Mendel sells for $799 on Makergear and can print at 1/10 the layer height of a Replicator 2. Thats the same price as the Pandabot (well, give or take $1), the advantage of the Pandabot is that it auto-calibrates and is excessively easy to assemble.

Although the official spec lists a 100 micron layer height, technically, I see no reason why a Pandabot couldn't print at the same resolution as a Prusa Mendel. Having seen both a Pandabot and a Prusa Mendel in person the electronics and hot end are similar enough that there is really no reason they couldn't achieve the same 10 micron resolutions on the PandaBot.
