Matt, I suggest taking lessons from a small FBO or private instructor and plan to do it in as short of a time as possible if you want to spend the least amount of money. Many will simply incorporate "ground school" into the training. I never took or paid for official "ground school". When it comes time for taking the written exam, simply buy one of these books and go thru it a couple times just prior to taking the test. I scored 98% IIRC without ever taking an official ground school.
I also used the Gleim books to take my written exams for my A&P rating (Airframe, Powerplant and General) and aced or nearly aced all three of them without ever taking a course. When it came time for my practical and oral test, I breezed right thru also even though the examiner was sure I would do poorly knowing that I never went to a school for it.
