The lastolite HiLite 6x7' is an excellent addition to any studio, and ideal for those needing a portable studio! easy to pop up, and light,(I use 1 lumen 8sv 400w, which easily lights whole backdrop) contrary to many reviews I've read the train (free here, which give's exceptional value)was easy to obtain white look without the need to photoshop at all and this was with using only 1 Lumen 8sv 400w to light the subject and train from the front!
As for collapsing it back down, you might need a friend to help, between me and my hubby we can collapse it and get it in bag within 30sec's! (haven't managed to do this on my own yet). There are many "youtube" video's showing you how to do this with ease! I would recommend this to anyone, you wont be disappointed!!
