Be sure you test out the table before buying it. Lots of tables I've played with are very cheap and break easily after use. I think another way to test a good hockey table is slamming the puck as hard as you can across the table, and see if it flies off to the far reaches of the store.
The reason I say this is with some tables, you spend half your time LOOKING where on earth that darned puck went in the room because it flies off the table so much. I think I might be the youngest on this board...maybe...but that's what I remember. When I was a kid, I wish that puck didn't fly everywhere. So, maybe you're kids will appreciate that too, unless you want them to have fun playing hockey puck hide-and-go seek.
P.S. If the table is in the same room with your axioms, be extra careful
