I have one of the Trimetals ones. £450 or so when I got it. Solid, but not impervious. As others have said, it's only held shut with a couple of padlocks. which you could snip with big bolt croppers or cut through the aluminium arms in not much time.
So, the bikes inside are chained to a D-lock that's cemented in the ground (I cut a hole in the wooden floor) and secured with a chain.
Not just any chain, a 2m Almax Immobiliser IV. 19mm thick steel-boron links. £135 quid, plus another £70 for a Squire SS65CS padlock. It weighs about 20kg and has stopped me worrying about bikes being nicked.
(They're also insured on the house insurance, after telling them how it was all secured they were happy to consider it a "secure outbuilding".)
