Ham Radio Outlet. Luckily we have one in the Denver Area.
The "old" version of the Technician class manual is 12 chapters and around 300 pages, including a chapter full of the entire exam question pool. You read a section of the manual and then look through the group of relevant exam questions. I'm sure the "new" version is similar in size.
As Ken mentioned, practice tests are available at
www.qrz.com and are comprised of a selection of questions from the pool that you've studied from. I think Ken has only been studying for 2 or 3 weeks and is already "acing" the practice tests. When you take the official exam the questions are drawn from the same pool, just like the practice tests.
Once you have your Technician license you can get a 2 meter radio which is what most of us newbies have.
Go for it.
