Cartridge for Thorens 521 with SME 3012R arm

I need a recommendation for a cartridge for Thorens 521 with SME 3012R arm. The pre-amp being used is a Rowland Consonance that has a bunch of internal phono gain settings. Rest of the system is Warner Imaging 300wpc amp and Vandersteen 3a (to be upgrade soon). Price range for cartridge is $300-$800 new or used. Any thoughts would be a help. Thanks - Joey
