Pavane doesn't have a Mac version, otherwise I would have tried it--as I recall, he has some interesting and useful features that other programs don't--

Anyway, I just remembered that Finale has traveling reps who deliver a special presentation at various dealers--there is probably a schedule at their website, but you could probably also let a dealer near you know you'd be interested in attending if they set one up--

Also, it is worth knowing that many working arrangers/composers write in a sequencer program and, after they've got everything as they want it, convert it to notation--then they fine tune the score document--Overture is much better for this than Finale--
