Advice about getting tickets for Dolphins v Patriots, please

[York Phin]

I've just booked flights to go to Miami in December and i want to go to the Dolphins v Patriots game on the 11th.

Ticketmaster have some left, but they're very expensive and the private ticket sites are not much better. If it was just for myself, I wouldn't mind so much, but my wife will be with me and she's not particularly interested in football so it makes it expensive.

Is there any way of getting cheaper tickets or should I just take the hit and buy now? Thanks.

I bit the bullet and bought 2 tickets.
