I took BarBri and the 3 day and 6 day PMBR. I signed up with PMBR before they started limiting the discounts, so I got $200 off because of the ABA and signing up early. So it cost me 795 for both courses. I figured, if it will make me feel more confident, I'm up for it. I don't plan on taking the Texas bar more than once.
I thought the 6 day course was good, because it wiped out cobwebs from first year, and shows you where your weaknesses are from the start. You learn a lot by doing the questions and going over the answers.
The three day course is necessary. I know I saw some very similar fact patterns in the 3 day as on the exam. I recommend going and taking the practice test, at the site (some people picked it up and went home.) I think doing it there, under simulated conditions, gives you a sense of what it will be like on test day. I also recommend forcing yourself to sit there and go over all the answers. A lot of people only came back for the second day.
BarBri lectures are pretty good as well. But I don't feel like barbri's questions or lectures prepare you that much for the MBE. I think BarBri is better for specific state essays and the MPT.
I think its important to do what makes you feel comfortable. I think if you work hard at it, no matter what courses you take, and stay persistent and diligent about studying in an organized fashion, you should be fine.
At any rate, good luck with whatever you decide to do!
