a question not asked, and answer not provided here, is:
  "What are you actually trying to do with the netflow?"

Answers of the form:
  "Dos detection and mitigation planning"
  "Discover peering options/opportunities"
  "billing customers"
  "traffic analysis for future network planning"
  "abuse monitoring/management/investigations"
  "pretty noc graphs"

are helpful.. I'm sure other answers would as well.. but: "how do you
collect?" is "with a collector" and isn't super helpful if the collector
can't feed into the tooling / infrastructure / long-term goal you have.
