I have an Interfit Stellar 300 kit and I'm pleased with it, not sure how it compares to the Elinchrom and Bowen but it's streets better in terms of build quality than the cheaper sets I've seen in Jessops etc. and certainly does everything I want. One good point with these is that they use a standard S-Bayonet fitting so there's a good range of accessories available.

You say you need to be able to use your 430ex with this kit, why's that? I find setting up two studio lights and a reflector gives me more than enough options right now without trying to use another flashgun. If you really need to use it just set the other lights in slave mode and they should fire when your on camera flash does.

I initially used a synch cord connected to the camera to trigger the flashes and when having wires dangling about became annoying I used a wireless trigger that fits in the camera's hotshoe.

Don't underestimate how much space you need to do this well, lights so far from the subject, subject so far from the background etc. I often only use one light and a reflector or two in order to simplify the setup and make it more practical in a smaller room, especially when there are children around as reflectors don't need power cables.
