The first link I posted includes them in the kit, but they are a pretty simple thing, and I'm sure there are plans available to make one for not much money.
Ah, I ignored the kit link on the basis I have a pump (I'm currently overed from head to foot in Ali-oxide from dremelling 4 years of oxidation from the pump - motor was stalled from lack of use but generally banging it about it's sprung back to life). I have a manometer - came with the pump.

Venturi?, need a continuous airflow?, I suppose a NRV could help, but think I'll stick with the pump and a low-pressure switch. I've looked at the tables in the link - I think they'd work very well with sheet materials that would cover the vac table but I'm likely to want to play with fairly small boards (100x75) - think I need a table with smaller vacuum zones, so already looking at aquatic 4mm adjustable manifolds, miniature pipe benders and brazing kits. Well... it is the holiday season!
