Advice Requested: 10th edition OG question

Question

Hi All,

I have certain questions and would highly appreciate some guidance. I tried searching this forum for answers to these questions before I began posting, but wasn't able to find them. I apologize if this post, in anyway, refers to previously asked questions.

(1) Is Official Guide 10th Edition from ETS' stable and 11th and 12th editions from GMAC? Or is there a GMAC 10th edition Official Guide?

(2) I am working with OG 11 (have 12) and am looking for additional practice questions. I thought of purchasing OG 10 and read in forums that there is an overlap between 10 and 11 editions (supplements included). But I came across two links in Amazon.

Book 1: https://www.amazon.com/Official-Guide-GM ... 0886852404
Book 2: https://www.amazon.com/Official-Guide-GM ... 0446396664

Both these links point to the 10th edition but have different ISBN #s, dates and significantly different prices. Obviously, I am looking to buy a used book for less but am unsure what the difference is.

Can anyone help me here?

Thank you.

Are you in the U.S.?

If so, I have a 10th edition that has been sitting on the shelf for a few years. Maybe we can work out a deal. I'll put it on ebay or something just so I can at least get money for shipping. Unless you have another method.

I'm in the US. I have a deal on this book ready via craigslist. Thanks!

But, do you know the difference between the two books listed above? Thanks.

Do revised copies require a different ISBN? I know that book had a revision. That's the only explanation I have.

I own all 3 OG's:

OG 12
OG 11
OG 10

The OG 10 was revised in January 2003 and is 816 pages long. 
I do not have the 1999 edition but my guess is that may have included some info about PowerPrep and other items but not necessarily modified any of the questions (thus not requiring a new edition).

By the way, where did you find the number of pages in each of the books? I did not see it on the Amazon site.

BB,

I too don't know the number of pages. Not sure what pages you are referring to. But, the price difference is very significant ($299 vs $60 for revised) and that got me concerned for a while. It is not just in Amazon, but other websites like Half.com etc show very high price for the 1999/2000 OG 10. Anyways, 816 number is good. Also, as a crude check, the dimensions (from Amazon) for both these books are almost identical. So, I'd go for a revised OG 10 now for a much lesser price.

Thanks all.
