Welcome Gerardo! You can't go wrong hanging around this place, and getting a 150 to finish your license would be great!
My 150 is not 150hp..just a regular 100hp under her cowl. We had an STC for a 150hp conversion for our other 150 and are selling a number of things we had collected towards that project. Other folks here do have 150/150s and can certainly tell you more about the performance they see.
Glad you are inspired to get flying!
