Spoke to Ramesys this afternoon, we should get Business Edition through them / the SSAT Agreement with them, price for Business Edition is the same as for XP Pro, so thats around the £30 - £40 area dependant on if you get SA, buy 10,000 licences etc..... If I am honest, Enterprise doesn't really do anything for me or shout that its going to add any benifit to a lot of schools in my view, Business Edition will be fine I suspect. Although I think that a lot of IT departments will probably use Ultimate Edition in there offices as it is useful to have everything to play with.
