SANJINKO  The Universal Subversion Installer (10.4.x) is available at: http://downloads.open.collab.net/binaries.html Pre-built binaries that do not require Fink can be found here: http://metissian.com/projects/macosx/subversion/  
(Version 1.4.4)

ANONYMOUS  Try SCPlugin, which is TortoiseSVN for Finder:

(Version 1.0.4)

ANONYMOUS  i totally agree - subversion is great, but without a decent GUI i can't really use it - i'd like to use it for version management of other things than source files (media assets etc.) and i have many people on my team who would be too intimidated by a command line.

The IDEAL of course would be integration into the finder with a Tortoise style plug in, but that's not going to be really possible until (hopefully) 10.4.

In the meantime a Subversion version of CVL would be excellent.

Sven and SvnX don't really seem to be under much active development unfortunately - at least Sven has source code available, so maybe there will be some movement there.

ANONYMOUS  Great product. Now we really need a nice and stable Mac OS X GUI with more features then svnX or Sven.
