There is a batch of black CH341A s which are giving 5V instead of 3.3V - which is dangerous for flashing - so please try to get a green CH341A. There are plenty of them available from AliExpress / China. And about the test clips, you can find a small review of different test clips here http://dangerousprototypes.com/docs/Flashing_a_BIOS_chip_with_Bus_Pirate (double check that your BIOS chip is SOIC8 shape, otherwise that will be useless for you). The build is not difficult, there are plenty of manuals available online + a helpful community as you see ;-)
