Studio Bergstrom makes some excellent Star Fleet style miniatures. The FED Capricorn Survey vessel would be familiar to many a ST fan. It's similar to (OK, identical) the FASA Marklin Class of star ship from the 4 Years War era.
I recently finished painting up one and so I thought I would share it here.
She's a fine ship and well worth the buying. Solidly built and with lots of good details.
