No offense, but you might be a little late in the game. Presses should be easy enough to find (I've got a spare single stage I'd be willing to sell you if it came down to it), but components.. if you shoot .223Rem or .308Win, forget about it. A lot of the rifle powders are hard to find, and primers are hard to find. Handgun components are fairly easy to find, primers are still a bit of a hassle though. If you've got a local shop that's got some stock you might be in business, but I suggest stocking up as much as you can reasonably afford for right now if you do start - I'm talking at least 8lbs of each powder (1lb = 155 .308, 300 .223, 1,000+ .40S&W, etc), at least a thousand (if not a few thousand) bullets, and same with primers. Spent cases.. well hopefully you've been saving for a while.
Hopefully there will start to be some stock soon, but it's anyone's guess when at this point. Most of the online dealers are out of everything. I've had to order some 34gr bullets for .223 because I didn't stock up, and it's almost impossible to find 55gr bullets. I've essentially retired the .308 for now because I didn't stock that up either, and match bullets are hard to find as well.
