i love toirtoisesvn. i was about to recommend it when i saw the topic title. i'm not sure if there are any good alternatives. i really miss it since i use a mac now
i have a similar issue. i just use a shell script for that.
Code
svn update
offhand i think you can specify the paths. just check the documentation. you can program a keyboard shortcut to execute it, or put a shortcut on your desktop, or whatever.
