Now the prices are in the reasonable realm I'm thinking about getting something. The MkIII supposed to be out this March looks interesting. The website makes the upgrades sound worth the extra cost over the older version. Wondering what people think of this? The temp calibration sounds important (my room temp varies quite a bit and can go below 60F at times). I was thinking one of these would be nice to combine with the Model RR I've always dreamed of building--I'm sure I'd find other uses though. Building one sounds easy enough (I've been "building" PC's since the mid 80's ).
