<p>The price for RocketReview actually fluctuates a lot on Amazon Used section. Yesterday it I saw one for $30 WITH shipping, but right now it is around $55 with shipping. Honestly it is worth it since it covers a variety of strategies.</p>
<p>I suggest looking at this site daily, and when you find a cheap one in the $20-$30 range, buy it. If not after a week, then I would just go with the $50 one.</p>
