As I need a new keyboard anyway, this thread got me looking at options. The G10 looks best to me. I like that it can act as a USB sound device, yet use standard jacked headphones/mike. It does not have an LCD screen, but with my dual monitor set-up, I don't need it really.

G19 is awesome but $200+ for a keyboard is a little too much. So I went with the G15 and it's old and only has USB1.1 but still beats the piss out a standard key board. Looking at the Pro's and Con's, cash was the biggest Con for me.

i have the g15 and i rlly like it alot i like the light thing for the keys it has and the fact that it shows ur scores in games is just down right awsome!

Well I just bought a G19, I'll let you all know what I think after I've had a chance to play with it. Love my G15 so I'm sure it will be a hit!

G15!! I have had my for 3 years and it is still going strong

G15, I dont see spending so much for a G19 for a fancy LCD panel lol

Woh! Whats this! a mini G11?! http://www.logitech.com/en-us/keyboards/keyboard/devices/5902

My G15 is also still going strong after 3 years but its in Toronto which doesn't help me out here in Alberta.
Consider them pre birthday presents to myself (my birthday is next Tuesday).

The powered USB 2.0 ports are good too. Double the G keys also doesn't hurt (though they won't be completely useful for me until The Old Republic comes out).

My wife and I both got G15's when I built our new rigs a couple months back, and I have to say I absolutely love mine. I have plenty of USB esata and a firewire port on the front of my rig, so the 1.1 on the keyboard didn't really figure in.

i have a g 11 works well for me, i wouldent mind a g15 prolly will be my upgrade whenever this one wears out, i swear on logitech i used the z5500 sound system as well
