Economic evaulation program, best?

Dear members,

What is the best program to use to calculate cost effectiveness. Previously I used treeage when I did Markov analysis. It is very expensive and I want to be sure I choice the best program before I pay for a new treeage program.

Basic health economic evaluation, such as be able to add QALY to calculate ICER, QALY per year, number needed to treat and so on.

What do you recommend?

Best regards
