Yeah, a new TV is planned in the next 6 months. Before I built the stand I actually used to move the control panel down onto our coffee table and use the better TV, but have since left it how it is. I think the current one I've got is a 48cm TV, so I'm hoping that a 68cm will do the trick.
The Control panel is very stable how it is, I have a bit of rubber underlay (used for rugs) under it to keep it from slipping, but besides that, it seems to stay in place quite well. I was going to bolt it if necessary, but not yet

I have recently added a trackball, and hope to update the website soon.
