A quick question. I want to have an extra pair of brake levers for my mechanical disk brakes set at a different position on my handlebar(s), and I want the whole upgrade to cost as little as possible. Ideally not more than 50$, at max 100$ (so no ultra-hightech sport competition-grade stuff). What are my options? So far I've discovered only the thing called ["Cross/Inline brake levers"](https://www.youtube.com/watch?v=K2ZgNrS7hSc) They seem like the thing, but it seems to me they are a bit limiting regarding where you can place them. Are there any other relatively cheap options?

**Edit:**
Sorry for confusion, I had to mention I don't have a typical road bike's or cyclocross bike's setup. I'm riding a hybrid bike, which has a butterfly bar as a main bar, and a couple of high curved horns attached at its left and right edge. Horns allow me to sit almost perfectly straight, and the main (butterfly) bar allows to lean forward for a bit more aggressive posture when riding over rough terrain. So I would like to be able to engage my brakes from both those main hands' positions.
