I have been using a Nostromo N52 for a couple years.
It is a Belkin product, but looks exactly like the G13 above, prolly the same product with a different brand name stuck on it.
Anyhoo, I *MUST* have it play now, I love it, I don't see how people can play with a regular keyboard. It doesn't take long to get used to it, and resting your hand (just using your fingers) instead of holding your hand up takes a lot of stress & fatigue off your wrist. Often I hear guys say "gonna take a break, need to rest my hand"....betchya they are using a regualr keyboard.
What I do a lot of the time when I play, is turn sideways and kick my feet up on a chair, prop my right elbow up on the desk to mouse with, and pull the keypad into my lap & lean back. Very comfortable. I tore my lower back up a few years ago carrying a 60 pound boat battery up steps, and this is a VERY comfortable-on-the-back way to play. So effectively, I need the keypad for my back..... but it works great & I would highly recommend it to anyone.
I used have the belkin N52 and it was great , The one in the pic I posted is the Razer Norstromo , They bought the right s from belkin , Belkin know longer makes it (.BUT IT'S NOT THE G13 ) The G13 from logitech is completly different..
