I have for sale one of these:http://www.dealextreme.com/details.dx/sku.8758
I bought a couple for selling on ebay, but was told by ebay it was something I wasn't allowed to sell there, so I'm offering it to people here. It's $39.15 delivered at DX, which is about £19.58. I'll do it for £19 delivered here, via paypal if anyone is interested.
Before the auction got pulled on ebay, I'd sold a good few of them and the quality was very good, stifling gps reception instantly. The typical customer was the white van driver who wanted 10 minutes tea break/snooze without his boss tracking him.
The item is at home, but pictures to follow.
