i bought a Razer Tarantula and i haven't looked back, one of the best purchases i have ever made for my computer.
i love the macros (i use them for programs like Firefox. trillian, etc) i love the anti ghosting one it, i love the key response (the eclipse has the worst response ive ever felt in my life, its like a sponge) and then you have all the other nice features like the two usb ports, headphone, and mic jack on it. the battledock (which hopefully will have some nice features coming out for it soon)
