Yes, the Lee Classic single stage press is a great product, perhaps one of the best single stage presses on the market, especially considering the price. But I really like the breech-lock system because it makes changing dies so simple and quick
I have a Lee Classic Turret press. While it isn't as substantial as my Lyman Turret press it is a real work-horse and so versatile. I also like the fact that it is self-indexing, a feature that no other turret press has. I've reloaded thousands of rounds on my Lee Classic Turret Press.
I'm not a big fan of the Hornady locking rings, I really like Lee die locking rings but they can work loose over time. I use a combination of Hornady, Lee, and RCBS. I use RCBS reloading dies almost exclusively except for Lee Factory Crimp dies, which are definitely are best-in-class.
The Forester Coax press and the new Hornady single-stage press are excellent presses and perfect for precision rifle cartridge reloading but they come with a high price-tag. One of the things I like about a number of Lee products (not all however) is the value. For regular guys who are on a budget many of their products represent great value.
I have used several Progressive presses over the years, starting with the Lee Loadmaster. I then started using the Hornady progressive press, found it problematic as well, and then bought a Dillon 650. It's a great press but has a number of idiosyncrasies. My next Progressive Press purchase (assuming I actually buy one) will be the new RCBS 7 station progressive press. They are solid, simple, easy to swap out die heads, and easier to adjust quickly. But, they come with a heavy price-tag.
Lee really needs to re-design the Loadmaster, especially the priming system, and bring it up to the industry standard in terms of reliability and ease of use. It simply requires constant fiddling and adjusting, which is why I got rid of mine.
