Lighting my 75

I honestly wouldn't skimp on either, if anything save up for another week or two and get good quality stuff. I think you'll be much happier in the long run with good equipment.

$550 for these two and will be more than enough for you with expansion options in the future, unless you need to include shipping in your budget.
