Well, in terms of price, I'll post them from Amazon, since they're the cheapest from anywhere:

Razer Deathadder Re-Spawn:
£43.82

Razer Imperator Gaming Mouse:
£54.99

RAZER LACHESIS BANSHEE BLUE:
£59.99

So I was just going to get the DeathAdder and look into buying the keyboard if I don't find better, and a headset.

But yes, my grip is apparently palm.
