IWB, Projectors - Suggested suppliers? (Yorks)

Got a request for next academic year for three new interactive whiteboards, projectors (with 3 - 4 year lamp warranty - pref unlimited) and of course all the associated kit and installation charges.

So, can anyone suggest any suppliers to try, especially given that we're in the Selby area of North Yorkshire.

So far I have a quote from Roche AV for between £1,925 and £2,121 per board inc. fitting,etc.. so I'd like to see what else is out there.

Thanks in advance..

I think I may have posted this before but we had a terrible experience with Roche and won't be using them again. Apparently it was due to the contractors they used but we were left with a shoddy unfinished job - getting them back to complete it was a nightmare. We still have a set of duff speakers that they are apparently coming to fix. That was months ago.
