We really like these desks. We figure they can fit six students comfortably and they have computer holes built in. They come in a wide range of colours. Sizes are 600mm or 800mm height. 2400mm long, width 50mm. Cost for 600mm $395, 800mm $515. We think 600mm is fine because we don't need to worry about the body of the desk. We think we would need four of these desks @ $395 per desk. This comes to $1580 (worked out in Saul's brain). BUT we also need another low table.
Total costs for four desks is 395 dollars
