I applaud you for your drive and energy to make the device you describe.....but with the advent of todays ISP chips, using Cygnal type parts as a prime example, do you think there is enough longevity in the market for the it?

No, probably not. I don't expect to become a millionaire overnight by designing a programmer like that...

But I need a programmer like that for programming the many non-ISP devices as well as for reprogramming old chips. The programmer I have only supports a limited number of devices, so I can either:

1. Buy an expensive programmer.
2. Try reverse engineering my current programmer to add extra device support.
3. Design a programmer myself.

1 is not an option as I'm cheap and poor :-)
And I think 3 may be easier than 2.

If somebody else can use the programmer, and I can sell a kit or two that's just an extra bonus.
