Sam, if you can spring for it, go with a Dillion. As stated, the service from Dillion is great. As Dillion states, " No Weasel Words" used to squirm out of a problem. And yes I own a Dillion.
I know people that have tried to use a Lee and they reaped disappointment every reloaading session. A lot of stuff breaking constantly.
The Dillion is at its best when you use the Dillion reloading dies. They are designed to be used with a progressive high output system. Expensive but can't be beat.
With the Dillion, I can load 1000's of rounds in just a couple of hours. In fact, gathering the components for reloading is the biggest problem now.
Also, I have several RCBS single stage presses, so I know how slow it can be to load a couple of 100 rounds for a shooting session.
The only thing the LEE press has going for it is the low price. Why not search for a USED Dillion??? Got to be some around. They are so durable, that unless they have been in a fire or hit by a train it would be a good deal. Also , Dillion will treat any press as if you had just bought it from them. Or at least they have in the past.
