I'm not sure if you're interested in Kickstarter projects, but myself and a friend recently backed the Raise 3D printer. They seem to have some pretty nifty features and will be selling with an upgrade to dual extruder available for $200 (if they don't reach the stretch goal for it). The N2 and N2+ seem to be a really nice size and resolution is said to go down to 10 micron layer height.

Might be worth a look if you're willing to wait a couple of months before shipping

I'm currently using a Rapide Lite 200 but it lacks a dual extruder and a lot of the snazzier features of some of these newer machines.
