Probably not worth it on a cheap bike, but when I replaced the fork on my hybrid, to move from suspended to rigid, I made the move to a threadless headset as well. This would add the cost of a headset, a new stem, star nut, top cap and possibly some spacers, but it is an option to provide more forks to choose from.
