Well, to compensate for my families lack of imagination, I went out yesterday and bought myself a Marantz Dolby 5.1 home theatre sound system (new for a ridiculous $1500) and a secondhand Mitsubishi LCD projector I spotted in a local pawn shop (a steal at NZ$800 when the new price was US$6500).
All I need are a load of bean bags and Mission Set-Up-The-AV-Room will be complete! Whoop!
I can't understand why a locally made leather lounge suite costs $5000 though, considering the price of the sound system. There's no logic in that from what I can see. The price of raw materials in NZ is pretty expensive, all things considered.
