Opinions on gaming peripherals

[likwidneo]

was looking to pick up a few items to optimize my PS2 experience, specifically:

and

http://www.newegg.com/Product/Produc...82E16826104281

and wanted to get everyones thoughts on these 2 pieces.

not too familiar with the mouse brand but its got the best reviews on any mouse with 6K+ dpi res and 7+ buttons. also looking for a good gaming keyboard, but i haven't been quite convinced yet by anything i've seen. i'm not into the split keyboards or funky designs. some good anti-ghosting support and macro functionality is a good start, but what else i should be looking for? I have always loved my RF wireless keyboards, but I'm not sure how much of an impact that has on input lag. plus i haven't seen anything in that field from any brands that i trust.

closest thing I've seen so far was:

any input would be greatly appreciated.
