Looks like an easy build - I have a table I threw together much like that.
I have considered adding modified keyboard drawer slides and swing out cup holders as well.
4 X 8 plywood - 50 bucks for oak veneered - 30 bucks for MDF
4 "X 4"legs - 16 dollars - cut down 4 X 4 studs
2 X 4 bracing under the top - about 20 lineal feet - 10 dollars.
1 X 6 or 8 trim to go around it - 25 dollars
circular saw - 50 dollars, if you don't have one - add another nice blade for 10.
Plexiglas for it, the most expensive part - 150 dollars.
time to build with a friend - about 4 hours.
buy some stain or paint - I like paint if MDF. 20-30 dollars.
Basic table without plexi - 100 - 150 dollars, assuming you have the tools.
Add plexi, 300-320.
Drawer slides - people throw them away all the time - you probably have one in the garage. add some plywood to it, install on the underside.
...you know you have to post a pic now...
