I've booked on with Javelin for a nice slippy December track day, currently £99 for the full GT circuit which sounds like a bargain.
Bedford is a great track for beginners. It's a long lap so doesn't tend to get too congested (apart from right at the start as per usual), and there's only a couple places where it's actually possible to hit anything. You can definitely get a good feel for the car.
Let us know if any more want a pre-Christmas winter track fix!
