Hi Mark,
Just wondering if you've seen my recent reply to Brian
here?
It would be helpful if you could give me an idea (or post a photo) of the area you have to work with - how dark it is - what kinds of things you'd like to be shooting etc. It's my personal belief that studios need studio lighting, not speedlites - and if money isn't an overly great concern then something that you can adjust and control from the camera will make life easier (eg start with a pair of Elinchrom BXRi and a skyport transmitter).
If you're still on the same phone number, I can get Peter from Apix to give you a call (and hopefully some sharp pricing).
The other thing I do like to stress though is that the lighting is just one part ... light modifiers are another ... backdrops and stands are another ... and that's just the beginning. I started out with 2 lights - then discovered I needed 3 for some looks - then discovered I needed a couple more for get another look (you can tie up 2 lights quite easily just lighting while seamless paper so that it's white and not grey).
Not something everyone needs right away, but something to keep in mind. Have you considered jumping on a plane and popping down to have a look at my setup? (pretty cheap if "grab-a-seat" is playing ball!)
