Cheers Minty, thats some good info there.
To be honest, Im not really sure about budget. Some of the kits Ive been looking at start from about £199 for a 2 head (1 softbox, 1 umbrella) combo; and as Im not going to use this for much more than family and friends (at the moment while I find my feet), then Im at pains to spend more than about 300 in total.
As for space, Ive been given the OK to convert one end of the garage to a white-out area, and its got loads of power points free so thats covered too. No natural light to speak of there as the window is covered by branches from the tree, so it will all have to be lamps.
I actaully had a look round a local studio on Monday as I was getting some shots on my son done and asked the 'tog if I could have a nose about. He was fine about it, and its looked a pretty simple set-up: 2 flash heads (both softboxes) and 1 constant light covered with a honeycomb.
