Comments and suggestions

If you're having trouble deciding between Sauna Std and Sauna MS, start by purchasing Sauna Standard. This makes sense because you can upgrade with full credit during the first year after purchase.
In general, Sauna Standard is suitable for simple models of heat sinks, circuit boards and boxes with one or two boards. If you plan to create detailed, "stackup" models of chips, Sauna MS will be required. Similarly, if you wish to model non-uniform boxes with 3 or more boards, it is likely that you will need Sauna MS. But, once again, if you're not sure, start with Sauna Standard. Both products are sold with a 60 day moneyback guarantee.
