I'm glad this thread is happening, because it would be good to know if there really are adequate quality knockoffs available for $50 range. My experience is limited to sample size of 1. If Steve is correct and I have the Kmise neck, and there is a different manufacturer, then maybe the other ones would work without modification.
Attached are pics of the knockoff neck along with an old Striker and Starfighter neck. The Starfigter guitars get hated on understandably, as the body is lightweight plywood of the crappiest variety, and the metal hardware is garbage, but I was surprised this neck actually looks not bad. It is straight, RW board is just as thick as first-gen Striker (which is in fact thicker than Focus), and the overall shape looks identical to a couple "rounded-pointy" Focus necks that I have. The frets on the Starfighter neck are not quite as fat as a Striker or Focus, but these were never played, so they are still nice. But yes, the rest of the Starfighter guitar is garbage.
This knockoff neck also looks to be a nice neck except for the wrong shaped heel. Nice thick maple board, nice profile, nice frets without sharp edges. My plan was to correct the shape of the heel, probably paint over the fake Kramer logo, and maybe use on a utilitarian guitar for my son and his friends or maybe donate for music therapy where I work. Whoever painted it did a decent job with the paint, logo and clear, but they got lazy and just buffed the clear without first sanding it to a level surface, so it's shiny but not flat. And there is some pixilation of the Kramer logo plus a very thin line running through it if you look real close.
Anyway it's getting late, so here are the pics.
The frets are perfectly aligned across all three necks in the shots of the heels, so the wood shape should be identical in all three. See for yourself:
