Another IKEA solution. Buy a piece of the kitchen counter top rather than a desktop - 3x as heavy and waterproof (check the damagedbin to get one for $10). Then add the legs from the do it yourself table range and add an extra one in the middle at the back.
Then you can have a 3m long desk for $50 that will hold an array of large CRTs
