I'm still mulling over getting a Sagem HD-45, my choice is due to the following factors. I will stand on my current unit (the built-in stand rules out the Sammy 50"), which my four year old daughter can't open yet. The size is right for my room (and the wife) The price is right (almost anyway) I think it looks the business I've see many good reviews I've spent many hours in Comet / Currys trying to address my concerns, these being... Frosted screen (I can't see this at all) SD performance (after playing with thee settings it seemed fine, both for Sky and Ch4 cricket) Rainbow effect (I have see this rarely when trying very hard) What would be helpful to me is to know the details of the colour wheel specifications, but I have not been able to find them. Could anybody tell me the speed and number of segments in this design? I wondered if any current owners had see this in the user manual (just a wild guess), hence the thread title. My current plan is to wait for more details of the digital version of this TV due for Christmas. If this is the same model with a digital tuner replacing the analog one the choice will depend on price. If they have upgraded any of the features (DVI to HDMI connections, more than 1 HD connection or a faster colour wheel) then I may wait on the new version.
