What scale of reloading do you envision? How many rounds per session do you put downrange? The answer to that will tell you whether to go cheap and cheerful (Lee) or more upmarket with the snobs (RCBS, Dillon etc.).
The real money saving in reloading, however, isn't with the 9mm, which is available fairly cheaply in commerical form (see Marstar etc. for $200/1000 factory ammo, or Wolf Bullets for $150 for commercial reloads) but in .45ACP, .357 Magnum etc.
