While I believe the GCC Expert 24 is capable of cutting Rhinestone Templates, it is powered by a Stepper motor. This motor type cannot withstand the abuse that cutting through the Rhinestone Templates will cause.
If you are looking to primarly do this, then you need to look for a cutter that has a Servo motor.
The GCC Bengal is identical to the Expert 24 and has a Servo motor. It is more expensive though. I have seen them at around $750.
