Ok, before the "Lee is crap" people start weighing in...
I have Challenger press and several Lee dies along with Hornady and RCBS. I also have a Lee Autoprime. I bought the press in an "Anniversary" kit back about 1987 or so. I managed to finally break it about 1999. The cheap pot-metal casting used to connect the steel lever to the press ram failed during full-length resizing of .303 British brass. Apparently a common failure, that part has been redesigned. And apparently it still occasionally fails.
My opinion of the Challenger press? For about $35.00 it can't be beat, but if you've got about $100, get something better. Mine still works, and I still use it.
For priming, I haven't seen anything I like better than the Autoprime.
For neck-sizing, I'll take Lee's collet dies hands-down over anything else.
For standard sizing & seating dies I haven't found Hornady or RCBS to be significantly better than Lee. Others might. Especially if those others are precision benchrest shooters (which I am not) and in which case they would stay away from Lee anything anyway.
If you're a first-time reloader, or on a tight budget (or both) a Lee Anniversary kit is a helluva deal.
Oh, and I have no personal experience, but I've been told the "Perfect Powder Measure" ain't.
