If you use macros, I would suggest using any of the razer naga series.
You can program the most basic tools/commands on the side keypad and it will save you A LOT of hand movements over the keyboard.
(I have del, esc, tab, ctrl, shift, L (line), R(rectangle), C(circle) plus a few macros for plugins plus 3 shortcuts for different curic pie menus. That way you can have almost zero toolbars on your GUI.
Also, the scroll wheel can zoom in/out with increments if you push it left/right instead of scrolling.
Edit: I just saw the budget. these mice are at the 100$ range but still I would suggest saving some money to improve your productivity (and thus make up for the extra cost with the money you will earn )
