RE: Finale and Music scanning software
I have both Finale and Encore. Even though Finale is the far superior product in regards to bells and whistles, I use Encore for more of my "daily" stuff. It's just a lot easier and faster to use. Sometimes, I'll do the "base" work in Encore, then save it as a MIDI-file, then import the MIDI file into Finale, and then finesse from there. I do have a trial version of Sibelius, but I have yet to open it up.
As for Music Scanning software, there are a couple of good ones out there. My friend, Steve, uses one of them, and he gets pretty good results. Since printed music is not all printed the same way (size, layout, etc.), there is a lot of finessing and finaigling you have to do, but once you get those settings set, the output looks pretty good. It's not perfect - you still have to edit things - and sometimes it's a little "too accurate", but it's a great timesaver if you have to transpose whole scores and parts. Steve uses it to make the rehearsal tapes for the Richmond Men's Chorus. He scans the scores in, then converts the files to MIDI, then plugs that into Cakewalk, then... You get the picture.
