I paid £90 for my Naga Trinity. The flexibility of it (3 mice in one basically, with those adjustable sideplates) makes it well worth the cost to me. So I don't see that as raising the Naga Trinity. Sure, yours is cheaper, but mine is more flexible. Plus, combined with the keypad I use, it's just insane. It's how I play the game.
That and my Naga Trinity is a perfect combo. It also all runs through Synapse 3, creating endless possibilities. How about a hypershift key for example to change things on my mouse (like I could have a hypershift key to change the DPI switch buttons on my mouse to toggle party members temporarily while I hold the HS key).
Context for members who didn't see my previous post, here is the mouse I'm referring to:
EDIT: I am officially an idiot. Just remembered, I could use the scroll wheel for party members, hypershift it to target enemies. But the hypershift being able to affect the mouse AFAIK still exists. I can definitely however map multiple profiles to my mouse and use my keypad to change the profiles.
