Razer looks like an awesome mouse. I use a Hewlet Packard of 1080 ppi, but before that it was a cheap mouse, but always look for one that is big (my hand is wide) and has a wheel that scrolls smoothly, because that is very important in Hexagon and other apps. A rough scroll is horrible.

My tablet is a Packard Bell. My wife uses a Wacom. I like my Packard Bell because it is really fast and accurate, although Wacom's pen looks more solid and good in general.

The monitor I use is an AOC of 17'', I recommend AOC because they are pro monitors at affordable prizes.

Also, I use Magic Formation as software to open apps. I constantly open and close many apps while working, so it helps me a lot. My pc is very hacked at a software level.
