We provide advice on the phone listening to your requirements we are able to help you get the right one as we have trained staff . We have a network of installers to cover your area. On higher end models we can arrange a loan or demo. We think most people should buy HD resolution , they are so affordable now and you wouldn't buy a 5 year old laptop so why buy SVGA which is over 20 years old. Yes XGA & WXGA are ideal for simple presentations and education use but we have all been use to decent home TV's or high resolution phones or tables so why put a huge image on the wall/screen which is inferior. There are some great brands out there BenQ, Infocus, Epson and less known ones like EIKI or Vivitek. Yes you can buy the wrong one, this is why we still offer advice rather than just an add to cart website. We have a price promise, we see the models, we often put one against another and see which one is best. We only buy UK stock,which has higher warranty standards to ensure you get real value for money. We don't sell the cheap brands as the lumens isn't verified. Look at our name it tells you that we are committed to this product and we have a great reputation in the market place for price and customer service. We supply the UK but also in Ireland, we offer a 1-3 day service to Ireland.
