Razer T is an overpriced piece of junk, it picks up dust and dirt and scuffs faster than you can say 'razer'.
Logitech G15 is a very good kb coming in second i would say is the eclipse 2 or g11
For mice you have the choice of the:
G7
G5
MX518
Copperhead
Habu
Deathadder
revolution
imo, if you want a cordless mouse the g7 is mile ahead of anything else, it doesn't lag, its responsive, has 5 dpi settings you can adjust and is comfortable.
For corded the g5, copperhead are neck and neck, copperhead, is better from my experience out of the two, feels lighter and more precise.
