Broadcast Option for Upgrade

I am in search of a replacement for my Sony HVR-M15U. We use it for a specific function so I was wondering if Blackmagic had a equivalent solution (obviously with newer technology). With all the RCA and component connections, the Sony is just outdated. Any thoughts?

If you are using the HVR-M15U for a specific function then it's quite handy to tell us what that specific function is.. As in, what are you looking for?

Currently it is used for both capturing to computer (iMac) for recording as well as secondary output to a CCTV system. That really is all it is used for. The onboard storage is not used at all.
