Just joined. Just got into the audiophile bizz after acquiring an AKG/Grado. That's my mini-introduction.
I have 3 keyboards, actually. I have a 6 year-old Saitek Eclipse (I, not II), Logitech DiNovo (not the Edge), and an Apple wireless mini keyboard. The Saitek has been the most reliable keyboard I've used. I've never had an issue with it. But after 6 years, the tactile response and dirt and grime (as well as the difficulty in cleaning it) between the keys are starting to really get to me. I'll most likely be upgrading to a G15 or Razer Lycosa.
The DiNovo and Apple keyboards are both wireless. I use the DiNovo when I'm not gaming and there's a ton of clutter on my desk, main keyboard for gaming and everything else, and the Apple for when I'm in bed or feel like stirring things up over IM, since it's the easiest to type with.
