I can't help you with cost. Just a word of caution. Cypress is soft. It's nothing like an oak or maple. You will get the "used" look quick using a soft wood for a table surface. Just my 2 cents worth.
(I used to build custom furniture years ago up north.)

Your top would be any more than $6.00 per bd ft for a rough slabs that you can glue together, Theres a few good outlets on the web just do a search for cypress slabs,
If you decide you want a walnut or redwood look us up,
And yes i agree with the previous post about cypress being soft, We use to build everything out of cedar but being also a very soft wood, we now use a lot of walnuts and maple,for table tops, but i do love the cedar.
Check out the pictures i have posted here for a few nice samples.
Have a great day
That's a great looking gaming table!
