You get what you pay for in the end. There is a reason dillions cost a bunch. Simply that they work all day, everyday.
My dillon has paid for itself.
Over the lifetime of the press, what is the difference between 300$ and 900$ when you've loaded hundreds of thousands of rounds for 50x the cost of that press and the frustration (or lack of) fixing it, or resetting it up.
Same as a gun. Own it for 20years, 500$ in ammo a year and your 250einfield vs your 1700bench rifle means nothing next to ammo costs.
True, to some people $600 isn't a big deal, to others it is. But the costs for other extras can increase the cost difference quite a bit more. For instance, since I load for about 30 different calibers, I bought an additional turret for each caliber, so as to not have to remove dies etc. A Lee turret is about $18, whereas a dillon tool head is $65, for a difference of $47 for each caliber. $47 x 30 calibers is another $1410 difference, plus you would need a variety of extra dillon shell holder plates at $90 each.
Dillon case collator is $500 ish, Lee is $18. Lee bullet feeder is $45, Dillon significantly more. Etc, Etc.
Time to change calibers on a turret press is under a minute, significantly more on a dillon. Time to refill primers on a Lee, 60 seconds, significantly more on a dillon
Point being is every system has its strengths and weaknesses. And a lot of which system will provide the best value, often depends on what type of loading you do.
So it's really just a matter of finding the press best for your situation. But no need to be critical of others choices. And sometimes the snobbery can have the effect of keeping a prospective new reloader from giving reloading a try if they don't have deep pockets.
