^ I need a table like that, chipboard top, fairly study but foldaway - I dont wanna pay loads for one - any ideas?

sounds like an excuse for you to use power tools

Pasting table and reinforce it yourself with some more strips of wood?

Its fairly simple to make a table yourself, providing you dont mind it not looking too professional.

Top, suitable bit of plywood with 25x50mm laths fastened on back by screws. Legs are fairly simple to make out of 25x50mm.

Chipboard might be rigid but its also heavy.

aluminium tube, sheet and a TIG welder.
