The Pro|Solutions Pro|Type from Razer is one of the best keyboards out there. The unique combination of an iPod dock and keyboard makes the Pro|Type a nice buy because you get the functionality of an iPod dock along with a great keyboard. Not only does this keyboard look great it also performs extremely well in games and other applications.
This feature packed keyboard can be had for $130 which is the same price as the Razer Tarantula. Both the Tarantula and the Pro|Type are excellent keyboards, the difference between the two is the bundle. Where the Tarantula has some "theme" keys and a "Battledock" the Pro|Type has an iPod dock.
I can definitely recommend this keyboard to anyone looking for a gaming keyboard and an iPod dock. The only thing that I can put my finger on is the color. Because it's white it doesn't really fit in with the rest of one's black / metallic colored peripherals.
