Headless are typically expensive because a lot of parts have to be made specifically for headless - bridge, truss rod, nut, and however you do the end of the neck. I find them to be lighter overall and better balanced/more comfortable, even though they still look weird to me. I would definitely buy another, but they're not for everyone.

I am definetly getting used to them the more I see them. Love how compact they are. They look like I can curl in my desk Chair or Spin around Like crazy in the bathroom with them... Not that I would try that
