You could buy one like BB opines.
You could have someone make one for you. I'm not in Beaumont, but if I were, I would.
But.....for the ultimate experience, you should check out this thread:
And build it yourself.
Yes, the thread is long, but you will learn all that you need to know about the UDS. My neighbor and I (he was curious about the noise I created making my double barrel smoker) put one together in a single day.
Can you use a drill? a wrench? a screwdriver? a punch? Can you draw straight lines with the aid of a ruler? Can you count to 30?
If you said yes to all of these, you can build it.
