Table saw won't do this,
Table saws can do a great many things. Most depend on the levels of skill and creativity of the user.
I've just touched the tip of the iceberg on mine not long ago, but making my own jigs and fixtures has yielded much more complicated joints than that one.
That's two passes through the machine right there.
But I wish I had more space for a true craftsman level of saw. Unfortunately, I've had to modify a contractors grade unit with a sliding table to fit my needs. I'm limited to the size of pieces I can feed through and to a certain extent, the accuracy with larger sizes. My workshop limits my table saw, as I have to fold it up and hide it away for other stages of building.
So to answer the original question, I'd spend as much as you possible can. If you do it right the first time, you'll buy something that you'll pass to your children, and possible your grandchildren. If you cheap out now, you'll have this same search again in your lifetime.
Cast iron sounds nice.
