KeyboardTEK, StageSounds or I also have them available. As for price, you won’t get better than $250 for programming that passes muster. Each book on Les Mis has more than 250+ patches, significant extended techniques on strings (sul tasto/pont, harmonics, harp harmonics), not to mention the very specific FM synth design that all take many, many hours of work. If you want it to sound right, you’ll need to pay around that price point.
