I see the Mises Institute is selling both volumes of Logic of Action for $125. I am tempted by this price (seeing as on amazon.com each volume sells by that amount). However, are most of the articles in Logic of Action likely to pop up in Economic Controversies? If so I may as well wait for the latter.
Search @ gemm.com (under books), leads me to the first volume of Logic of Action being sold seperatley @ $85.75, but I do not know of the 2nd book you are asking for (economic controversies did not turn up a search, oddly).

Economic Controversies is a compilation of Rothbard's writings on economics that the Mises Institute is publishing at some point this year. Is supposed to be over 1000 pages. Apparently a lot of the articles are ones found in obscure journals or high-priced publications.
Oh, that would explain why I cannot find Economic Controversies as it hasn't been published yet, lol. However, I did find a slightly cheaperr listing of Logic of Action Vol. 1 @ $77.95 ($3.00 shipping): http://cgi.ebay.com/The-Logic-of-Action-I-Method-Money-and-the-Austrian_W0QQitemZ300190814419QQihZ020QQcategoryZ378QQrdZ1QQssPageNameZWD1VQQcmdZViewItemQQ_trksidZp1638Q2em118Q2el1247
