I have been looking around for a few weeks now and have been largly scared off getting a ceiling mount. Soooo expensive for what they are. I was looking in Mackros yesterday in the slight hope they might have a cheap one but there wasnt even one there.. (not that surprising) But... There was one of something left, "Vivanco Video Bracket". Its made for fitting a VCR to the underside of a tv arm bracket.. but i took it out the box, dry fitted it.. and at £4.99, ill be damned thatl do for my projector mount! I havnt put it on the ceiling yet, but when i do ill post a pic. Found this ebay listing of one: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=320059482897 Just so you know what the box looks like if you go hunting. Mackros have them in stock currently. This would I imagine fit any projector, as it has adjustable width and height with foam pads for protection on the contact points. I have a PTAE900, it fits easily and holds it firm. The only slight un-perfectness is that it wont tilt or twist out of the box. But then if its a fixed mount you want then that shouldnt trouble you. I may add a wedge to angle it slightly.. but will see when i get it installed. Hope that helps the bargin hunters out there!
