Here we go again, sorry Wammers I don't think you have any concept of the number of man hours that goes into producing the software for this type of kit, just coding all the error messages is a mammouth task. Once it's written, it's not all profit, there is ongoing support, updates to correct errors that surface in the hands of users not to mention continuing development for new models.
The poor sod has actually done us all a favour, without his kit you would either have to go to the stealers or fork out for Autologic.
Anyone with the get up and go to gamble on investing time and money to produce this sort of stuff is IMO entitled to make a good living out of it.
And no I have no connection with BBS Guy or Blackbox solutions but I did used to design and manufacture micro controllers in my own business so I have a pretty good idea of what is involved.
