I would probably suggest one of the Ortofon OM Pro carts, if it needs to be for DJing.
The main reason for this is whilst the standard OM carts (like the 5E) will sound a little more balanced and detailed, it tracks at a much lower weight, meaning it will be more prone to jumping out of the groove when people are dancing around, and the bass bins are doing their thing.
If it's for home/studio DJing, then I would stick with a Hifi cartridge, with the OM5E / Audio Technica AT-95E / Goldring Elektra being good starting points around £35, then to the Ortofon 2M Red and AT-120E at around £70, then the 2M Blue / AT-440ML at around £120.
Hope this helps...
