I'd say you got a good deal. The SDB press has a lifetime warrenty that goes with the press. It doesn't end when it gets sold to someone else. See what pistol caliber you want to make a lot of and you will be able to put the Dillon press to good use. It isn't all that hard to set one up for another caliber once you have the conversion parts and dies.
Bullseys powder is not a favorite of mine. It is too easy to double charge a case with it.
Just start with a straight wall case type to get you started. I hope you have a .357 mag pistol already. That or .38 special will probably be one of the easiest things to load. .45 acp is very close to being the easiest. Start small and keep good notes of everything you are doing. It will be helpful later on.
