The logitech as well as the new naga is too fat and awkward. If comparing these 2 though, the logitech feels more solid.
The corsair model is weird, but feels nice and solid and, once you get the hang of it, is a good choice. Looks cool too.
The old naga is the best design and feels solid enough. You will here nay-saying of razer quality which I'm all for since the blade is an overpriced POS.... but the naga and other mouses are really pretty nice.
I have no experience with this one (i think its newish), but it looks pretty good: http://www.amazon.com/Redragon-Perdition-Precision-Programmable-Cartridge-profiles/dp/B00GU8W5AE/ref=pd_sim_vg_1?ie=UTF8&refRID=0FS9CSQZ86VXC2GP7QGV
The naga is fine as far as hitting all 12 buttons accurately goes. Your thumb and forefinger are your most dexterous fingers and I'm right handed so that makes it even easier than with my left hand on the keyboard, not to mention I can't reach 7, 8, 9, 0, -, = without moving my hand.
You only have to memorize where 1, 4, 7, and 10(0) are and from there you just need to practice +1 and +2 until you have the entire pad memorized. --- Every time I try to go where I really wanna be it's already where I am, 'cuz I'm already there XBL, PSN, Steam, Origin, BSN, GFAQs, MC: PhilOnDez
I don't like the g600/naga, I find them cramped and uncomfortable.
G700 is the way to go. It has 7 buttons and is far more comfortable. between ctrl, alt, shift, that gives you 21 hotkey access through the mouse, and realistically that's all you ever need short of certain bloated MMO monstrosities like the EQ2 beastlord. --- Irony is a maginot line drawn by the already condemned
I like my G600 a lot better than the two Naga's I had before it, although now Razer uses the same design of the buttons(two grids of 6 buttons that are angled so they are easier to hit) so it basically comes down to if you want the smaller size of the Naga or more features of the G600. --- Billy Mays: July 20, 1958 - June 28, 2009 The Greatest
