Series 7 study materials?

hello, i have passed the CFA L1 and PRM L1 and would like to get the series 7 cleared.

I found that there are basically STC and Dearborn/Kaplan

For STC, it costs $230.
And Dearborn, I was looking at

http://www.kaplanfinancial.com/kfs/product_detail.asp?product_id=581&media_type_id=1&state=&topic=

it costs $160.

I just wanna pass it with minimum effort and money cost.

Can anyone comment on that $160 Kaplan thingy?

thanks
