Three more keys - for your feet.
OzBargain shows it was $41.99 in September.
The upgraded model is $59.99.
The reviews for this one are pretty solid, but you're not getting durability. Hard to tell how much of the breakage is caused by foot stomping rage quitters.
The software might be tricky. There's reference to a CD in reviews, for those with a reader. A comment in the last OzBargain post said Linux support might be coming. This is not my area of expertise, and might be what keeps me away. Any experts have advice? I think I'd find it useful.
I got this to use as a healer in WoW back in the day.
