Ok... well I got a quote for £599 from RocheAV for a Hitachi EDX12 XGA Data/Video Projector but also got some bad news in that our older Sahara projector has been mounted too far away for the projectors available today..

So it seems we have the additional cost of moving the mount to contend with as well..

On the up side I found out that you can get lamp warranty included so it seems pretty good all told..

Thanks for the input folks...
