Talking Roms can be quite controversial as a subject, and you seem quite excited over the prospect...Burners are all different, that is to say they are only as good as the chips they support, as result you are looking at a substantial investment in time money and most likely multiple machines (many on obsolete platforms)...The Q4 does work, and would consider it an excellent entry level machine.

Doing this cheap is not really an option, I thought that at one time...But the chips won't work on a bad board, so many years later, you will also have a couple of oscilloscopes, a solder station, bins for storing parts,processors, flip flops, rectifiers, power supplies, frequency counters, UV eraser and bla, bla, bla..I got about 10k into my simple cheap chip blowing project...and that was on the relativity cheap end (IMO) since I calibrate everything myself with a 10MHZ frequency standard.
