Your overall size is odd. But, in the past, I've purchased solid core
wooden doors and "banquet table legs" to fashion nice looking tables.
This gives you a *real* wood table that you can stain to your needs.
[You can also purchase folding saw horse legs (i.e., just add cross
member to make your own saw horse -- of course, if making a TABLE,
then no need for that intermediate step!) Many "banquet table legs"
are flimsy]
For a semi-permanent installation, a couple of 2 drawer file cabinets
(one each end) are a good, practical alternative.
I've used an arrangement like this in my office for 30 years. It
has served me well -- despite having four 100# monitors on it at
one point!
