Best wireless keyboard? pics!

well the topic pretty much says it all. i built a new rig and am looking to get a wireless keyboard so that i can use my desk when i'm not using my computer.

here is pretty much what my desk looks like:


i probably wont be using the keyboard further than 5 ft from the base receiver so extend range is not an issue. i also dont care about the mouse, i have a mouse i like and will just be using the keyboard. i still game a little so i'd prefer something with no lag.

i havent settled on anything, but heres what i've seen at newegg.
none of them really jump out at me as the clear winner and all of them seem to have been getting some pretty poor ratings and comments from the users at newegg.

Logitech S510

42@newgg after MIR and its 40 at compusa if i were to go get it in store

Logitech MX3200

60@newegg after 20 MIR and its 100@bestbuy/compusa

Logitech LX710

Logitech EX110

i know all the ones i listed are logitech, but they all seemed to have better reviews than the microsoft counterparts.

please if you have any experience with wireless keyboards, i'd love to hear your advice. i probably wont be buying one until this weekend and i could use all the help i can get.
