Recommendations for pop up background

[Ferj]

I know stuff can vary in quality etc but I'm looking for a pop up white /black background with a train and wondering if anyone has any recommendations?

I have a Photodeals one, think its 2.2m x 2.2m which has been great over the last few years. Also now have a 7x6 Hilite which is excellent
