i got the logitech 700 lx and love it. I picked it up for $40 after mail in rebate so i really like it. the keyboard is very slim so its nice and doesnt takeup a lot of room. go here casue its cheaper than newegg and you can get free shipping, it got to my house in like 4 days
I have a microsoft wireless desktop. Perhaps not the "best" but it is good. The battery life is a few months(what I was mostly concerned about) The mouse is nice, but the smooth scroller wheel can mess you up...
