I have been very pleased with my LEE challenger kit.
The LEE quick change bushing are great also, they make switching dies a snap.
I added the auto prime to the challenger press ; much nicer press priming than priming by hand ,the attachment cost $20.
Other than that I havn't added anything besides the dies , tumbler and a Lyman book.
If you check on ebay there is a store called "reloaderschoice" ; best prices and quick shipping , he is a US soldier to boot.

Whatever you decide on, good luck.
