Good book on Epicureanism

I’ve been wanting to buy a new book on Epicureanism. These are the two I’ve found on amazon:

http://www.amazon.com/gp/product/0872202410/sr=8-2/qid=1302184470/ref=olp_product_details?ie=UTF8&me=&qid=1302184470&sr=8-2&seller=

I’m wondering which one I should buy. Any suggestions?

I believe ‘The Epicurus Reader’ has all of the material of ‘The Essential Epicurus’ plus a little more.

Also, you may be able to find all of that material at this site: http://www.epicurus.info/

Thanks a lot!
