The choice of the press mainly depends on what volume of ammunition you plan to reload. I, for myself, own a Dillon XL650 because I shoot close to 400 rounds of 45ACP per week and reloading them with my single stage (thing that I did for 4 years) was getting way too much time. This way, the 1000$ press will be quickly repaid. If you shoot very little, I would say to go for cheaper equipment.
Dillon products are top-of-the-line for the high-volume reloader. They come with a bullet-proof warranty too, but the price is high.
Hornady presses such as the lock-n-load progressive is quite good too, I've heard nothing but good comments about it, and it seems that the warranty is not bad neither, plus, it's cheaper than a dillon.
Lee is the entry-level reloading equipment. Cheaper and very good for the price. It's usually a good starting point for the reloading rookie (I've started with lee products, used them for 4 years, and I'm still using them for loading the calibers that I shoot less often, as Dillon XL650 conversion kits can get pretty expensive)
You'll probably need a different press to reload your shotgun (I'm not aware that there's a press than can do both metallic cartridges and shotguns shells). But I can't help you much more than that since I've never reloaded shells.
Also, the press isn't all you need : one or 2 reloading manuals, a scale and a caliper are must-haves for reloading.
