Question on Amp Head

Okay first post, so I'm purchasing an Orange OBC410 cabinet for Christmas and I was wondering if anyone knew what would be a good head to put together with it for around $500-$700, maybe a little bit more expensive if necessary. I've looked around, but I am uneducated when it comes to Heads and Cabinets, so I was thinking the smart guys at Talkbass could help me out.

Thanks.
