Update - these turn out to be silver-finish plastic; reasonably well made, my fault since I obviously didn't read the description properly (or wasn't paying attention when I did).
I've managed to sell and send everything I had on eBay apart from Innocent Blood. I'm down a few quid on the laser printer and the media player thing, well up on the print server, so reasonably happy. And I've finally shifted the bloody Indiana Jones movie!
Today's charity shop bargains were Burn Notice seasons 2-5, Castle season 1, and Doctor Who (new Who) season 2 - all for £30. A good few hours of mindless entertainment reasonably cheap...
