Some years back I was going to make my own but found lightly used
teak one on craigslist for around $100. So I figured it was definitely worth it. Later on, when I had a second boat I came across a very similar table for it, also on craigslist, for all of $50. But that one was not
teak and somewhat heavier. And painted with plastic type
paint but seems more robust than teak one so I'm keeping it as a possible spare.
But yes, they're easy to put together if one is reasonably handy.
