Hi Everyone - I have been thinking of getting a DLP set for some time now and am particularly taken with the Samsung SP50L7HX - had a viewing in John Lewis and was very impressed. However, I did notice that if I "flicked" my eyes from side to side I could see the dreaded rainbows but it seemed OK if I didnt move them. Is this likely to cause fatigue if I watch the TV for extensive periods? I also noticed this set on the American Costco website: http://www.costco.com/Browse/Product.aspx?Prodid=11067561&whse=BC&topnav=&cat=4848&hierPath=79*4848* I dont know the model number etc but it looks pretty cool and well priced. Anyone know if it is to be sold in the UK or is already available? If so where from? Cheers for your help guys!!
