(Let's) save money.
To be honest, we've actually already found the perfect dining table. It's more a matter of finding a way to afford it.
(I don't know how to make a direct link, but look for "Domino Legno" in the tables section.)
At its standard size, it's exactly right for our kitchen, and when you extend it, the legs are still in the corners, unlike a lot of extending tables. However, it costs about three times as much as we had planned to spend on a dining table. I think I'll throw a 100 yen coin in a jam jar for every time I remember to take a bottle of water to work. We should be able to afford it in about 20 years.
