Prodigy vs Core Concepts

Trying to decide between Prodigy and Core Concepts for a test simulator.

It looks like Prodigy offers up to 700 questions, on a downloaded software...for $185.

Core Concepts has up to 3 - 125 question online exams...for $100. But it seems that the exams are 1 time options, with review of results for 2-3 wks after.

Any feedback from recent users?

I bought both, and I would recommend the core concepts final exam package. I didn't like the couple of topic exam packages from core concepts, but I thought the comprehensive exams were the closest to the certification exam of all the practice exams I took form Valley, Prodigy, or Core Concepts. Prodigy has a lot of old material, and basically repeats the same question over and over a lot of times. Also, prodigy has old information in their exams that won't be on the exam, and they don't address the new style of questions very well.
