I can sell the change log tool that I got developed (yes I wrote the specifications) that is far more intuitive with loads of selections and full context help for every field, program and FM's used in the program. Written 100% in a language understood by most humans.
Cost will depend on bank balance of the client. For those struggling to make ends meet, I can give it for FREE in a text file.
For those who need fancy stuff to justify some jobs :-), the cost will be well.. how about 100 USD. with 5 year free support ? I don't think its worth more than that actually
Thanks
