Did not want to clutter up Markie's Free Setup thread, so I am starting a new one here.
I have the Fender guitar work pad/mat that has the built in neck support, but I just ran a Google search and found some other interesting ideas.
Here is one that resides in a case that opens up, pretty cool.
Wow, $500, pretty steep for what it is though.

I like that one in Markie's thread, much simpler.
