Get a 2.5A power supply whether you go for the zero of the 3B.
If you want the cheapest Pi, then yes, the Pi-Zero is it. It also has no analog audio (only digital via HDMI), no built-in networking capability (of any kind), only a single USB I/O port, and no header installed in the GPIO port. Also, the USB port is micro, and the HDMI port is mini. So you are going to need even more accessories with the Zero than you would with other models, which partially offsets the lower price. And lets not forget it's roughly 7-8 times SLOWER than the Pi3 (1GHz single-core vs 1.2GHz quad core) and only has half the RAM.
The fact that they could even make a computer for five bucks is pretty impressive, but I don't think it's a good choice for a beginner.
The only two models powerful enough to be used as desktop computers (unless you have the patience of Job) are the Pi2 and the Pi3. Not speedy desktop computers, mind you, but still fast enough that you won't want to do this:
And right now the Pi2 is even more scarce than the Pi-Zero. You could save ten bucks on a model B+, but you'd be giving up a huge amount of performance, half the RAM, WiFi and Bluetooth. The Pi3 really is the one to get, unless you have a very specific project in mind that you know a Pi-Zero would work for (and then, good luck finding a Pi-Zero).
My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups...and where is that annoying music coming from?
