My own contribution:

These four are indeed the currently available concept modellers based on
LMT (Layered Manufacturing Technique). The Modelmaker stands apart here,
as is is primarily accurate, and not fast. Your requirement for both rapid and
accurate will be difficult to achieve).

Please do also consider using CNC based RP systems for concept
modelling. These are cheaper by far, and offer a free choice between
speed and accuracy. Which type is better (LMT or CNC) depends on the
type of model that you need: LMT is best for small, geometry with many
inner details (thin walled), CNC is best for styling block models (solid).
