Reply to DIY Mobile DJ booth??

Just wondering if any of you have made your own mobile DJ booths?

I'm pretty sure my set up used 7 lives yesterday. I DJ'd a staff party in pretty tight quarters with the dance floor right up against my standard folding plastic table.

Almost lost my a laptop a couple times and was most concerned with something bumping against it hard enough that either the laptop would slide off or the table would just collapse. I'm looking for something that would protect my gear better and that I can trust will stay standing. Just wondering what anyone has done for their own mobile setups
