If you get the MX-USBISP-V3.00 boards that don't have the three solder bridges then they are super easy if you have two or more.

Just use one as programmer and the other as target, connected by the 10 pin cable that comes with them.

Jumper the target between the indicated vias (a cut leg from a 0.1uF capacitor makes a perfect removable jumper).

Get the standard Atmega8 latest firmware from fischl.de and flash using avrdude with 'usbasp' as programmer.

I set up various DOS batch files for testing connection, backing up original firmware, restoring original firmware and flashing the new firmware.

Once set up. it literally takes about 20-30 seconds to jumper a programmer, plug it in to the ribbon and double click the batch file to flash the latest firmware.

Once set up
And that is the big step for many folks
since there are so many different versions of the circuit and PCB layout floating around out there
and many people don't want to take the time to analyze their PCB and put their
tools in place to do the update.
As with many things in life, the actual time to do the task is minimal, it is
the prep work that takes all the time.
