Visualisers: can anyone help me with what to look for?
I've been tasked to look into the purchase of some visualisers by a teacher who has used them successfully before (ie. not a "wow these look good let's buy some" request!). But I have never dealt with these before, and have no idea what features to look for, what brands are good, etc. We have SMARTboard 660 IWBs and laptops that are mostly XP Prof SP3, though we have a few Win 7. I can find companies who sell them, but don't know if they are any good. Anyone had to purchase these before? Help would be very much appreciated.
