I currently use a Logitech G430 headset (after my old G930 broke down ;C), a Sharkoon Draconia Mouse and my trusty Microsoft SideWinder X4. I always wanted a mechanical keyboard but I simply couldn't justify spending 60€+ on a keyboard as long as my old one still (mostly) worked.
The headphones look the most interesting with the wood on the side, but I've always wanted a mechanical keyboard and this one looks really good, so that's my favourite.(and yes, favoUrite)
