budster, I've got no dog in this hunt, but let me say this. Greg Grimes is one of the guys that keeps this board relevant. It has, based on my 20 years of BB postings on everything from guns, computer software, fishing, fire fighting, zombies, etc the best info available.
I don't know Greg, and might not even like him if I met him, but don't diminish or classify his value to this board based on his occupation. I had no clue he was even in the aquaculture business. That says volumes about his ability to keep his postings and business separate.
As far as the cost of feeders, I certainly get your point. Feeders are expensive, but providing protein or slinging corn is not the same as feeding fish. If one of my deer feeders doesn't throw, then no harm no foul. If my fish feeder quits, then I lose fish.
I've got several inexpensive feeders that are so old that American Pickers would love them, and they're still working. But, that's the exception. I've also got $300-$400 feeders that I work on every year.
I hope your WGI feeder gives you and me, many years of dependable service, as I have one also.
