I'm going to be sensible and go with the Lencarta Twin Kit. I understand I don't need a background kit, but I've really enjoyed using the one I borrowed and with my mother being an interior designer I have plenty of nice materials to mess about with! Is it worth getting twin softbox kit, or a softbox and umbrella? I've only shot with umbrellas and found them a little harder to use in tight fitting spaces.
I'll create a for sale thread in the Classifieds tomorrow and move on a few lenses that I can do without. When I've earnt some money through the studio I can re-invest this back into the kit bag. Thanks for everyone's help, I'll get some images up of my progress as soon as I start snapping!!
