Rega P25 cartridge upgrade

Hi all, 

I would appreciate your advice and opinions regarding a cartridge upgrade for my Rega P25.

My current system:
- Rega P25 with Grado Prestige Gold.
- Marantz PM6004 
- Neat Iota speakers (http://neatacoustics.com/iota/)

I listen to a broad range of music from electronic to jazz to rock.

The Grado Gold came with the Rega when I bought it used a few years back and unfortunately the stylus appears to have been bent during a recent house move (dont ask...). I thought it would therefore be a good time to upgrade the cartridge. 

I'm using the phono stage on the Marantz amp which is listed as only compatible with MM. Music is important to me and I'm keen for a great sound but dont think I've got time to get lost in exploring MCs and phono stages etc currently so feel like a good quality MM would be sufficient. Looking to spend £200-300 max.

A few potential options I've discovered:

- Ortofon 2M Black
- Goldring 1042.

Any thoughts or experience would be appreciated. 

Thanks

Thom
