Thank you guys for your considered opinions. I have asked Teachers what they want but they don't actually know until they get hands on. I guess most Interactive Screens have similar characteristics and functionality. The question really is, Cheap and Cheerful but potentially problematic with after sales support or pay a bit more for Smart, Prometheon or C Touch but get a decent brand with good warranty support etc.
In fairness here, it sounds like Sahara have ironed out some of the old Clevertouch issues and their offering a good priced product.
I had a recent quote for a CTouch Laser Air+ 65" IP (Oktopus Software) with 7 years on-site Warranty + Training. All Brackets, AV Plate and installation for £2'224
Anyone got any comments about this product or price?
Many thanks again guys.
