Thanks guys, almost forgot this thread, didn't expect to even get any replies since I was just updating my link

I made the whole thing out of solid oak, it's easy to work with. The top of it is edge glued (2 pieces running the width of the unit) to avoid warping etc etc... actually that's a tip right from Norm himself

just saw your board down the center and flip over and reverse one side and glue it back together. No biscuit joining tho, just a straight edge glue.
I went with 3/4" material so it would be strong so I could pound on it when losing a good game of Missle Command

and it gives plenty of room for the rescess.
Yes a 3/4 round over bit is what you want for doing the edges. I then also make a special sanding block for the edges: take a small block of wood (maybe an inch or two wide and drill a one inch hole thru it, cut the block in half so that you bisect your hole... then you can lay a piece of sandpaper in the half rounded (convex) portion of it, then sand away on the edges

tips... hmm, buy good router bits! the cheap steel ones go bad after nearing using them once

if you want a nice rounded edge like I put on mine you'll have to stay away from veneers and edge stripping... you could use the plywood for the base of the unit but I think it will turn out better with a solid top.
Good luck with however you decide to do it!
