In actuality, their NLE plugins are actually what's priced wrong. I know no one here wants to hear it but when you think about what NV is doing is incredible for the price. It's taking often poorly shot video and making it useable. How much would you have had to pay for lighting or a better camera? Probably far more than the $250 price of NV. Since I cut in Avid and FCPX as well as grade in Resolve I have a lot invested in NV and don't regret it for a second.
Remember, at the end of the day this is a business. We can't expect prices to be dirt cheap and then turn around and charge premium prices for our services. We have to be realistic about these things. Ben, I would say approach them about a group buy. They may have done one on Reduser a while back. That at least seems like a fair way to approach it. Maybe they get a nice bump in sales and you get a bit of a deal. Everyone wins there.
