I've read a lot online about knockoff magsafe cables but the only part I need replaced (due to international Macbook) would be the "duck head" and I found one online for $5 (http://www.trademe.co.nz/computers/apple/other/auction-557869763.htm). Obviously the brick and cable would have some special sauce inside (that's why the knockoff's suck) but would a prong have the same issue? I think (seeing as it's a just a prong) it's probably fine (coupled with a genuine Apple magsafe brick/cable)
