All good choices. I don't know the Monarch folks. Big Gulp, you should have them contact us...this is a good market for good products. Since I don't know them, I deleted the url in your first post. That's our policy. We love the opinions, but won't allow sales solicitations for a company we don't know.
There is one thing about all feeders. They are machines. Machines break and/or wear out. Because of that, I have chosen to work with the companies most willing to be customer service oriented.
I know Zach Sweeney. I knew his dad, the founder of the company. Zach has always been responsive to issues with his feeders. Larry, I would call Zach and tell him the issues. I bet he acts on it...in your favor.
I'm getting to know Chris Blood quite a bit better. He's a key cog with Texas Hunter. I'm seeing more and more of their feeders in the field and everyone I speak with tells me they are quality products. The hoppers are large, too...don't have to fill them as often.
I'm regularly conversing with Ron Ferguson of BA Products, makers of Aquapro Feeders. He is earnestly working with landowners to figure out and solve issues they have had with products in the recent past.
Moultrie is working harder to service the fish feeder market and tap into their fair share. Their products seem to be improving, too.
There are others out there, too. Feeding fish is becoming more lucrative for the feeder companies and I expect there'll be more of them surface in the not-too-near future.
The only feeder that throws the big pellets is Sweeney's Big Mouth feeder.
When Dr. Griffin designed Aquamax Largemouth, I contacted Sweeney, Texas Hunter, AquaPro and All Seasons. The only one interested was Zach Sweeney. One company was battling its own product fires and wasn't capable of R&D, another was working to acquire another company and didn't have time and the other one was too busy to be interested. That was two years ago.
