Kaplan Premium Online Course vs Other Online Courses??

Hello,
I 'studied' for the GMAT for approx 2 months. By studying I mean that I did 5 Practice Exams through the Kaplan Book. I generally didnt review the material very much that I had gotten wrong as I sort of tricked myself into believing that simply seeing more problems would allow me to get the score I desired. The week before the exam I spent about 2 hours per night dgoing over the common math equations/rules that the Kaplan book provides.
My objective is to get into a part time MBA Program. My practice exams were all in average range of what this school was looking for so I figured that on test day I would do as I had been doing.
I thought I went through the test fine, felt confident and then reality set in: I scored a 430. Ugh.....dejected I sent the scores off the the school and I was expectedly rejected. They told me that everything else on my application was very solid and acceptable and just want me to re take the exam.
After an initial feeling of disapointment, I have committed myself to ensuring that the variance between my practice exams and my real score is not so dramatic next time. I had been scoring in the 520-570 range on all 5 of my practice tests so to get a 430 was pretty shocking. The avg test score at the school I have applied to is a 560 and they are looking for me to score near that.

I need to develop better study habits and have conviced myself that self-study is not the best method for me. I need more structure and direction.
I work full time and live in a somewhat rural area where Kaplan classroom courses are not offered as frequently. I need to re take the exam by Nov 15th so plan to study (more appropriately) this time until then. I can't locate a course that I have the time to drive to that also finishes up in time for the Nov 15th date.

I think that a structured online envrionment would work the best for me.
I have looked into the Kaplan Premium Course as well as their Basic Online course. Preimum Online seems to be well regarded, the basic is the same info/process as the premium but with fewer CAT's, no ultimate test, and non-interactive. The price diff is $700.

Considering my situation, in that I am not looking for a 650 or even a 600. I am looking to score a 550-600 essentially which unfortunately I have already done (albeit at home)
Which online course would you recomend for me? I am more interested in learning the material as opposed to just going through more practice problems. Quant is definately my weak point but could use help on Verbal as well. MY AWA score was a 5.5 so I'm ok with that.

Any suggestions/experiences with any of the available online courses would be helpful.

Thanks.
