A quick search is showing me new machines in the $7k range. You could probably pick up a used one for a few thousand less. This is cheaper than I would have thought, honestly - a decent full MIG rig is not exactly cheap.
The materials cost is really not very high (no idea on the laser itself, but the rest is easily <1k. Probably <500.). The R&D cost was probably very high to start (but also coming down).
