I am using it professionally for a lab. The best bang for the buck right now is to buy their starter pack which includes library prep kit and 2 flow cells. This is limited to one per person. I got two members of the lab to buy two starter kits, effectively getting the flow cells for ~500 each. I am sure a lot of people are doing this too.
