I recently bought a properly heavy duty table to take two 60 litre tanks after a fair amount of looking (photo below) and was really impressed with the one I found here on eBay (seller's eBay username is Industrial81). I think it would easily take a tank as big as the table surface. One tip though, the top is made of reclaimed wood and not perfectly flat so I cut two pieces of ply to provide a level surface for the tanks, this is in addition to the supplied mats. There is also plenty of wood to drill into to add hooks on the underside to keep the cables tidy. Journal to come on the tanks.
