A bit of an eye opener!!

I'm pleased to see the SW ED80 comes out well.

ED80 are not all equal. As well any other mass production telescopes.

My internet service provider really doesn't like that website. When I click 'continue anyway' there is a great repository of telescope optics but I get absolutely bombarded with dodgy popups that won't let me shut them down without ctrl-alt-del

Hmmm
No other negative feedback from others....

Mark.......... I get the same warning page - the BT version anyway - but when I click 'continue' it takes me to the page as shown in Merlin's post above with no pop-ups or other problems. I think the warning page is an ip 'filter' (I'm on BT Infinity) rather than an anti-virus one (I use Avast).
