My initial choice was a Mead series 5000 14mm UWA which Bintel have listed for $285. I've read favourable reports, in some of the cloudy nights forums, on that particular EP and it's a tad more easy to justify to the Minister for houshold affairs than the Teleview.
I also found a review on UO EP's at

More reading up required methinks.
Has anyone had a look at any of the Series 5000 EP's yet?
