i got the sato racing ones. you want ones that go into the engine mounts and not the fairing. the sato ones look nice and match the bike well. about $60 i think and 10 mins to install.
another thing i did, since i'm still sort of a new rider, is turn/switch my passenger pegs around. i will never ride anyone, so i figured i'd use them as another set of sliders.
to do this, take the pegs off, and then put the left on the right and right on the left, and then flip them upside down. this way, they still look somewhat normal, but can only be flipped down. so if you have them out, and you crash, the peg will brace the peg/muffler mount and you'll loose a peg and maybe the mount, but save more of your bike that way.
