You reckon you can squeeze $100 a pop out of this crowd? Can I be there for your trying that magic trick?
I agree it is on the lower end/kindness prices for SMD repair and modification but in my experience it is far higher than most would be willing to pay for such work. Such a thing being mainly why I don't do any non software projects for games world -- so many times over the years I have seen something I could fix, fired up an electronics cad or mechanical cad program, ran the numbers and while I don't mind having some fun I would rather not end up out of pocket.
I dare say the poster of that was thinking as the mod chips could be seen as a less than legit item one can not really call upon the law to fix it. See also you can't go to the police if someone sells you fake drugs/drugs not up to spec.
I am hazy here on what might go. Some might point to various court cases (though they seem to have to renew the ruling on their being legit or not), it might fall under a DMCA exemption, might be something else that troubles it. Depending upon the nature of the mod it could also change it -- you can hire me to install a microcontroller/fpga/cpld/some programmable chip on your device all day long, you turn around and program it yourself and that is all you. If my soldering bridged something it should not, came loose, was in the wrong location... then I have failed in my service.
