So many different budget prices and models for the Optoma's. i.e. HD600X, HD66, HD67, HD200X With the HD600X coming in at £389 its very attractive at that price. I youtubed a lot of these and the HD66/HD67 looks very good but at around £500. Is there really £110 difference between them ? Then there is the Acer H5360 at around £480.
