I have the little pink one also and I love it. I have seen some people use it at shows, but it they had it on another table. We have taken a little fold up table like the one in the link here. Wal-Mart has one like it for about $15.00. It doesn't have an arm, but it's lightweight, portable and reasonably priced. I cut a Rubbermaid sink liner to the size of the table so they wont slip and it worked fine.
