G-15 keyboard is what I've used for a few years now and love it. For one thing they are very durable and mine is still working perfectly. I ran through cheapo's like crazy.

The G keys have lots of uses. One use for mine was to find rare mobs. Just made the macro and had my G key repeat. Also has the ability to run several macros at once and have them automatically repeat.

For example I made a macro just using the macro record feature to strafe my slaves left and right automatically during heavy movement fights.

Anyway- think I paid 80 bucks US 3 years ago for my G15 and it's been worth every penny and more.
