Those look nice, but they do seem a bit spendy. Can't remember what pegs I have just now, but seems like I spent around $100 bucks. I need to look it up.
Edit: I have Rivco pegs. Similar to those above, but round instead of flat. $55 for the pegs, and $35 for the mounts, so $90 all in. But those above do look nice, no question.
