I used to use TortoiseSVN 'cos there was no free VS integration for SVN (VisualSVN[^] is $49 a piece). Then came a stable and full featured version of ankhSVN[^] - version 2.1. Now I use ankhSVN most of the time and only go for TortoiseSVN for stuff that doesn´t show up in VS. Believe me, ankhSVN doesn't get in the way until you tell it to do something.
