Whats best box on a budget?

Hi all.

I recently bought a skybox f5s on our favourite auction site with a 12 month subscription.

box seemed to be fine but all of a sudden it went off after only 2-3 weeks.

seller said it isn't his fault as server is online (off I mean scrambled).

anyway upshot is he is giving me my money back so im asking what is the best box to buy for approx. 100/150 pounds.

thanks.
