Suggestions on cartridge for the Pro-ject RM5 TT

What cartridge would be a good match for the Pro-ject RM5 TT. I know it was just reviewed with the sumiko blue point 2. I just auditioned this TT with a inexpensive grado silver. My dealer did not have the sumiko blue point 2. What other recommendations within the $300.00 range would be a good match. I will be using this with a Plinius 9200.

Thanks
