The camcorders are for high school use.
The first is for use by anyone, they may have no real experience. It needs to be a very easy to use camcorder with decent output that records to a built in dvd (stated requirement).
The second is for use by students in GCSE level multimedia work and two features required are good quality HD and record to an HDD. Price about £600-£700.
It may simplify things if they are both the same make.
I haven't looked at camcorders for a long time, so I don't know what's hot at the moment as models change so quickly.
