and with mice, I still use a old logitech one that cost £3 or so 5-6 years ago
Just because you're a silly, ignorant cheapskate, it doesn't mean Psygo has to be.
Considering that the keyboard and mouse are the two components of a PC system you actually touch and use the most, I don't see why you shouldn't spend that extra cash on some good quality stuff. I think I've had four or five different Logitech mice, currently owning a G7 LE, and my next one will bear the "Logitech"-logo, too.
