Found this nice DIY idea at Bungalow 5. By combining planks you can easily create your own tabletop, with endless possibilities when it comes to mixing surfaces and colors. Here thay have used IKEA VIKA LERBERG legs, but you can use all sorts of trestles to create your own look. I think Loop Stand Frame from HAY is great, they look a bit cleaner and sturdier. Of course they are also more expensive, but I guess either way you will end up with a reasonably priced dining table.
