What 1goodshot said. You MUST have a scale. Digital is nice, balance beam is just fine (I've been using the same one for 40 years). And after you have read the books, read them again. Don't hesitate to call Dillon if you have problems and come here for answers to any questions you may have.
P.S. Search the TFL Archives for getting started in reloading. Lots of good info there.
