I have a 22" LCD monitor that I use for business presentations and I do alot of traveling with it.?

I curently just carfully place in my back seat. I really need a travel bag. What are some bags or cases I can use that big to travel with ? Where can I buy one ?

Lots of them online. Google either Anvil cases or Gator cases

You Should definitely google Pelican cases. Find one the right size and then shape the foam in it to fit the monitor and any other fragile parts!

They are great.
