CHAINKING  Like the other poster, I was looking for an iAddressX replacement, which stopped working in Snow Leopard. I too was relieved. This is a great utility app, just as easy to use as iAddress and just as functional, if not more so. Well worth the dough, as it will get used on a daily basis for years to come.  
(Version 2.1.2)

CHAINKING  OK, there may be a problem with some serials not working (mine does and I don't lose it) and the developer not answering emails (for an app this widely used, he probably gets too many). But this is a great app. It works and does so with a sensible and easy to use GUI. When I need something that I can't or won't buy, I go to Acquisition and it hardly ever fails.

CHAINKING  William. Nice try with your fascist propaganda. You guys will beat the drum of the "liberal media bias" until the last dissenting (but correct) liberal voice is silenced. Hollywood? How about Schwartzenegger, Reagan, Charlston Heston, Mel Gibson? Until AAR, every single AM radio station in this country had a right-wing bias. Now that we have one, you macho rightie types start acting like the cry-babies you really are.  
(Version 1.0)

CHAINKING  I agree. The new icon is a big step backwards!   
(Version 4.0 beta 4)

CHAINKING  Just tried it on 10.3.5 and iTunes 4.7. Performed as advertised if not better, although I have only used it for small playlists at a time. Hats off to the developer!  
(Version 1.1.1)

CHAINKING  Highly recommend this one. Does what it says it does. Unlike GetInfo. I had hundreds if not thousands of folders and files that got their privileges altered (long story) and these had to be copied onto a new computer. Good luck doing this with GetInfo.

CHAINKING  I wrote the "buyer beware" post (see below) because the 8.0x "upgrade" was so poor. I am happy to say that 8.2 has changed all that. Am now glad I paid. I encourage all of you to do the same.  
(Version 0.82)

CHAINKING  Buyer beware. Just paid for v0.8 thinking that the upgrade of a whole decimal probably meant a big improvement in performance. The opposite is true. You can only connect to 6 networks now (before it was 12); there are far fewer hits per search; and a much greater percentage of hits never download (hosts are constantly offline). If the host is offline or busy, don't show the file!

My advice: Stick with 0.74 and don't even think of spending your money until the problems with 0.8 are resolved. (Yes, I have tried 0.802 and it is no better.)
