Thermal analysis software

We are thinking about investing in thermal analysis software and I would appreciate your recommendations.

1. Did you guys consider other packages?

2. Why did you select Flow Simulation over the others?

3. Was cost the primary factor?

4. Based on the what you know now, is this package still worth it or would you have bought something else?  What would you recommend?

5. How long have you been using it and are your designs simple or advanced?

Thanks,

Prashant
