I went through the process of trying to find a music scoring program to suit my needs a couple of years ago. I downloaded and tried several demos and trial versions. I settled on Noteworthy Composer. Cheap, easy to use, versatile enough to do all I required, midi in/out, good quality paper score. Neither I or the family have had any regrets at the choice.

Jed, try the options, and decide for yourself which meets your requirements.
