datruth: You've gotten some good, varied advice, and some accurate observations--how much you save depends on how much more you end up shooting.
I'll go a little further--
1. First of all, you can get set up for much less than $350.00 for the gear (not the components), but that amount really will cover everything from a tumbler and media forward to boxes for the finished rounds.
Without igniting "press wars" here, I suggest you google here, in this forum, about the Lee Classic Cast Turret Press.
This press can function as a SS press as you learn, as a turret when you load rifle, and as an auto-indexing turret when you get up to speed.
Here's an article that is an exhaustive review of it, and it also details his reloading experience with it.
This press will handle all your calibres--FWIW, start with a straight-walled pistol cartridge; .45ACP is an excellent beginner's round to work with.
2. About Glocks: Since I have blown up a Glock while shooting a reload, I will not recommend it. (And, no, I am convinced it was not a double-charged case, but that's another story.) However, aftermarket barrels are readily available now (they weren't when this happened), and it would be easy to change to conventional rifling.
3. Since you load pistol, I would NOT recommend you start with a Single Stage Press. Yes, you may eventually want one as well as the Turret--but that is another issue.
One last thing--as you start getting more and more (and often conflicting) advice here, think more and more about the "kind of" shooter you are. If you are "
process oriented"--and here, think about whether or not you enjoy the 'finer points,' like how you hold your firearm, like to shoot accurately and practice marksmanship techniques--then I would recommend the Lee products.
If you are "
goal oriented"--think about 'buying a box a ammo and shooting it up'--then you are probably should consider Dillon products.
And, ask any and all questions--people here will help a newbie get oriented.
