I could buy $100 non-geared mill every few years for less.
It really sucks whenever you finally take the plunge and get that nice new piece of kit that you've been thinking about for years and it turns out that it dashes, rather than fulfills, your hopes. As someone that has experienced that more than a few times, I'm sorry it happened to you.
It really sucks.
For what it's worth, my analysis of the situation has resulted in the same conclusion.
The Cereal Killer gets the job done, it lasts for years, and when it inevitably starts having problems you don't feel obligated to monkey around with it and subsequently turn otherwise enjoyable brewdays into exercises in frustration. My first Cereal Killer survived about eight years of 1.5~ brewdays/month. I'm currently on year four with my second. But I have very high hopes for this one because...
I've found that conditioning my malt has made a big difference in increasing the longevity of my mills. I was very, very hesitant to start conditioning because the mere thought of damp flour caking up my rollers and bearings seemed horrifying. Why on earth would anyone want to do something so stupid?
Once I took my brave pills and tried conditioning, though, I've found that my rollers and bearings are much, much cleaner because flour production has diminished almost to nothing. My mill cleanup on brewday requires no compressed air, just a paint brush. Better still--and this makes me nervous as hell--but I see no reason to tear down the mill and clean its working surfaces on a quarterly basis. There just isn't that much to clean up anymore. I've moved that out to a yearly cadence, but I may move it back to a half-yearly interval depending upon the results of this Fall's cleaning.
Best of all, conditioning takes, at most, 5mins tops? It's a lot quicker than trying to get a mill properly cleaned.
I took the plunge on conditioning for LODO reasons (frankly I found it made no tangible difference) but I'm sticking with it for pragmatic reasons. It's a bit more demanding on my drill, but it makes the brew day much easier and enjoyable while boosting my efficiency a smidge.
That's been my experience, for what it's worth. I hope you found this useful and I'm sorry your awesome new mill didn't work out for you.
