Try either the Sidewinder X8 or wait for the more expensive Razer Mamba to come dude.

Actually, you'd be surprised. The G15 was of similar pricing when it first came out. It's such a b*tch that in UK, whenever new stuff come out, their prices are unusually high (as a premium for new and rare stuff on the market). But after that, the price drops like a rock. You see the G19 selling at 150pounds now, a few months time, you'll probably see 60pounds in pricing.
