Logitech MX3100 cordless desktop.. wireless kybd + MX1000 mouse. it's awesome for gamming with it's lag free response and the many buttons on the mouse

I got mine a year ago around $80 after rebate..

want to get another one for my other system.. but alot of places doesn't seem to sell them no more and if they do they are $110+

is there a reason for that? is there a more updated mx desktop series? (yes I know there's a bluetooth version but I don't want to mess with bluetooth)

if so what is it?
