When I started kegging we were drinking "$30 homebrew pints" for awhile too. And they were well worth it!
But with time it has come down mostly to the cost of ingredients, and some electricity. Buying grain by the sack and hops in 8-16 oz packages keeps that cost down.
When we suggest a new brewer starting with brewing a few kits, we do not necessarily mean extract kits. All-grain kits are offered too by many vendors or piecemeal a few together at a local homebrew store (LHBS).
Many processes in extract brewing are the same as in all-grain brewing, except for steeping certain malts and dissolving malt extract (syrup or powder) vs. producing wort from malt and other grains.
Most ready-to-go kits, both extract and all-grain, come with instructions, alas, usually very basic or even poorly written. All in an effort to make it (look) simple...
My suggestion for reading John Palmer's
How to Brew, 4th Ed. before brewing or buying anything was not meant as a deterrent to start homebrewing, or force you to read it. Just keep in mind, it's a wonderful resource and reference for homebrewing.
Aside from it being a long, mostly abstract read, many chapters and topics won't make much sense until you've a brewed a few times, or want to know more of the nitty gritty details of how and what, most of it is all there. You may skip or skim as you see fit.
For a quick overview, there's a free online version of the (fairly old and dated) 1st Edition on the web at: HowtoBrew.com.
As others have mentioned, if reading isn't your path to quick learning, there are very good and valuable online alternatives. Our forums is among one of those.
Apology note:
I meant to write this last night if it weren't for the electricity in our larger neighborhood to go out. We also had a snapped power line lying in our yard, not sure what exactly caused that.

It all came back on a couple hours ago, and the line is back up.
