I followed a similar path recently when getting into reloading 9mm, except I chose to get my materials shipped to me and pay the hazmat (I did the math and I paid roughly the same and had a bigger choice of brands). I figured my cost is 12.5 cents per round.
Where I made a mistake is getting too many bullets without trying out various samples first. I got 3,000 124 gr. rn fmj made by Armscor; they have been fine in my P10-C, I read that the 124 gr. bullet was what the 9mm Luger was designed around, but how do they compare to something else? Is 124 gr. really what my gun likes best? A better approach would have been to get samples of a variety of bullet types and weights from different companies and see what does best. I will still do that, but that step should have come before buying in quantity.
There are so many variables with brands of product and how they are used, that you can stay busy for a long time trying out this and that. I am enjoying reloading about as much as actual shooting, that is a surprise.
I've been happy with Alliant Sport Pistol, and the Federal 100 primers have been good. Other shooters use different powders and primers and are fine with them, but finding a product you like and sticking with it has advantages.
So far I've been very happy with the Lee Classic turret press, I got it based on the recommendations of experienced people I trust. It isn't as fast as a progressive press, but I can turn out one or two hundred rounds in a comfortable time and it's easier for me to keep track of what's going on.
