and good luck with the search... as others said a good one is hard to find and cost a few bob.
I've been looking a good bit and in the end bought a hawkeye recently. There's a reasonably clean one near Tullamore which I got told about via contact in the Netherlands. Wasn't advertised anywhere here that I could find. Didn't see car yet, but pictures looked clean (as they often do -but my contact assured me is a nice example). If you're interested let me know and will forward you contact details of the person who told me about it.
