New systems for college use

Hi there,

I was hoping that I could get some feedback on the systems I am about to buy for our college (note this is a not a film editing course, and therefore the technical competence of our students is a little lower).

We have been using FCP and DV cameras - which has been working great but is now effectively obsolete. For various reasons we need to move on. I have a budget of £5000 (it cannot go mcuh higher than this - so please keep suggestions within this price range) to buy 2 editing computers (software needed for 4) and 4 cameras.

We currently have two Mac Pros, and for that reason I want to stay with Macs. I am currently thinking:

iMac (base spec) x 2 (£930 each)
Panasonic TM900 (£680 each)
and
Adobe Premiere (education version) (£300 each) (although FCP X is another optio)
total £5800

plus some bits and pieces like headphone adapters etc.

Thoughts, ideas, other hardware I should be looking at instead.

Any help would be greatly appreciated, as I'd hate to get it wrong with this kind of money!

Cheers.
