I have a 10 x 10 Pro Panel setup along with an extender panel, desk, matte bin and a smaller shelf bin. They are in like new condition and I'm happy with them. The only reason they are up for trade is I'm seeking a black setup to help my photography art stand out even more. The ones I have are moonbeam. There is nothing wrong with the setup.
If you have a black setup and are interested, I will send pics of all I have. They are the knockdown space savers panels, not the 1 piece panels. Makes it much easier (for me anyways) to break it down after a show and for fitting better for hauling. I live in Minnesota (Twin Cities) but willing to consider meeting in the middle somewhere.
