Any 223 Remington die with a 7/8-14 thread, which is virtually all of them these days, will work just fine.
Most folks that buy Lee presses buy Lee dies.
The standard for bottle neck rifle cartridges is a two die set, a resize die and a seater die. If you are loading for a semi-auto rifle, slide action rifle or a lever action rifle you will want to full length size.
For a bolt action rifle, you might want to only neck size. But only neck size cases fired in that particular rifle. If you get fired cases from another rifle, you will need to full length size them the first time you use them.
There is lots of different opinions on crimping the 223 Remington. i don't, even in my ARs.
Hope this helps.
