For those that decide on a bootcamp .. I've got a few emails so I'll expand a little on my experience.
I used Craft in Charleston, SC -

Small shop, great folks.
Days 1,2,3 were on the Redbird Simulator. 2-3 sessions, about 1-2 hours each.
On day 4 the flights in the airplane (DA-40 with G1000) started. 2-3 flights per day, about 1-2 hours per flight.
By day 5 I had zero confidence I was going to pass the checkride with just 3 days remaining.
On day 6 everything started to click.
By the end of day 7 I thought to myself "this is easy, why was I having such a hard time with it the first few days".
By the end of day 8 approaches and the radio calls started feeling repetitive and mundane and easy. A sure sign that the training was working.
I had to fly to another airport for the checkride with the examiner (who had no affiliation with the school). Interesting that the 30 mile flight was in marginal vfr and 2000 foot ceilings. I almost turned back to Charleston.
Nailed the checkride with confidence.
Another interesting story ... on the way back to Charleston, right after passing the checkride, the wx closed in on me with rains and surrounding storms. I almost filed in the air, on the way back from my checkride, it was getting bad, to say I was concerned would be an understatement. My options were going away fast. It was the heaviest rain I've ever flown in but ultimately Charleston just kind of automatically routed me through it without having to file. My fear of flying in rain ended that day and my confidence in ATC went up considerably.
I didn't read up on the KCHS before going, didn't realize it was a C130 base. All my fears of flying with big airplanes in class C were wiped away after a few days of my tiny, tiny, tiny airplane in the pattern with giant military aircraft.
It was well worth it and I recommend the experience. The intensity level keeps you focused. All in, including the DA-40 rental, was around $7500 plus hotel for 9 nights. If you do the math, you'll spend near that just tooling around with CFIIs in the local 172. If you spread it out, like most do, you'll spend considerably more due to forgetting everything in between sessions. I knocked it out in basically a week and a wakeup and came home confident with the ticket.
Like I mentioned in my previous post, it took me a few days to recover mentally. On day 10 I woke up just exhausted from the experience.
I had a hard time locking down CFIIs, they are very transient in our area and usually barely experienced. The actual schools seem to want you to enroll in a multi-month program designed for commercial pilots, very expensive.
Hope this helps!
