#188421 - Cost target?
Responding to: Richard Erlacher's previous message
In general I think that any new product must be developed in three phases:

A - make it work

B - make it good

C - make it cheap

I don't know where you got the target sales cost figure of $5K from, but that seems ridiculously cheap for any form of medical equipment. After all, I suspect the advanced prothesis cost more than that. I would press on with the concept you like best because designing it down to a hard cost target may mean that you just give up or you make something substandard that doesn't do the job. If you are first to market you will be setting the price expectation.
