Maths ocr mei revision guides?

Hi what do people think are the best revision guides for C2 and Further Pure 1 for ocr mei:
http://www.amazon.co.uk/Revise-MEI-Structured-Mathematics-Level/dp/0340957344/ref=sr_1_8?ie=UTF8&s=books&qid=1260106977&sr=1-8

the only fp1 guide i can find is like the c2 one but it doesn't come out to april, are there any other ocr mei further maths or other c2 guides anyone recommends or even some sites.
i already have this one
http://www.amazon.co.uk/Revise-MEI-Structured-Mathematics-Level/dp/0340957336/ref=sr_1_1?ie=UTF8&s=books&qid=1260107712&sr=8-1
which is good but a bit brief and can't find any other guides for c1.
any help would be great.
