What's your opinion on hand loading, how's the learning curve
Hmmm...how to address that.
First off, its right up my alley (and may be the same to you as well). In the same way I used to love assembling engines, I love reloading. Attention to detail and following the instructions are critical. I pay 100% attention when I'm reloading and its proven to be and abstract form of therapy for me as it gets my mind off of other things.
Concerning the difficulty...I really don't consider it any harder than anything else, follow the rules, don't deviate until you really know what you're doing.
There's a wealth of knowledge online. Look at a site like this:
http://www.hodgdonreloading.com/data/pistol
You can go on there, pick your caliber, pick your projectile and it will tell you nearly all the info you need to know. Case length, primer type, projectile seating depth, powder charge, est feet per second and case pressure, it's all there. All of the data you'll find on sites like that (there's tons of other powder makers outside of hodgdon, all will give you safe and reliable info for reloading.
Second, the hardware. I went middle of the road on what's considered to the one of (if not the) best reloading machines on the market, Dillon. I went with the 550, they also make a 750 and a 1050 but I didn't need the features they provide. I have about $1500 or so and that gets me the machine and everything I need to reload .38 special, .357 magnum, 44 special, 44 magnum, and 9mm. If one caliber is something you want, they make a machine that's called the square deal that reloads one caliber only.
Money savings? Eh...that's a completely different conversation. That all has to do with how much you shoot and what you shoot. In time, my setup will definitely pay for itself...but it will take a while. With the 44 special I've shot this year, I saved $300 over what I would have dropped on factory ammo...so whatever I've spent -$300...
