I realize you said free, but I haven't found anything free that works well for the variety of situations I end up supporting (family, non-profit, and corporate).
I use the $10 pass for 24 hour access to gotoassist.com. (think citrix quality remote support) I then try to do all my support in that 24 hour window for those people I don't help often. Some days I'm frustrated enough that the $10 is cheap for my sanity.
