Comair Academy, er Delta Connection Academy has a few. I think they went for $20/hr. Single and multi engine capable. I think we even had a jet quadrant for use, too.
Quick thought...check with your local Community Colleges. They may have PPL and Inst groundschools and you may be able to use a PCATD for just a lab fee or something. A lot of FBOs have them as a training aid for their instrument students, too.
