Hi Gang.............. I am looking to purchase a Back Ground Holder. The Photek S-4010 and the JTL JTL B-1012 seem to have about the same specs. and are available at Adormama at about the same price. Does anyone have any experience with either of these products and/or with Protek or JTL? Thanks..................... Russ R.E. Baker Photography rebphoto@pronetisp.net
