Hey /p/haggots, I have 800 dollars to spend on anything. What would you go for? (There will be no single purpose of the gear I buy, I would be interested in anything from flashes to macro lenses) (my gear as of now is pic related)

But in a broader sense: My philosophy so far was to buy all things cheap to get the most experience out of little as possible. Though I sought to get the best quality/price, I didn't actually care much about quality or pixel peeping. What is your philosophy? Do you think its actually better to buy fewer decent cameras? Why?
