The only current STC for the 337 is the STEC series, not to include the 3100.

Attached is the list of STC installations for the 337 based on the model. I believe the 55X is the latest and greatest, behind the 3100. I received a couple of verbal quotes for the 55X; with altitude preselect and a few other features*, you are pushing $30K. All the shops said to plan on another $10K to 15K for the installation labor.

*The base for the ST-603(T), which is the 55X for a twin-engine airplane, is $25K.
