Here's the deal: I just moved to Chicago away from my gaming friends (particularly our SAGA game we have going on)

and beyond that my job demands around 50% travel all over the North America...
I don't want to quit my friends (and the game/games we have) and i want to keep playing no matter where I happen to be as I am the only kink in the chain keeping them all from playing. They will all be face-to-face and my goal is to be attached via interwebs.
My question is how people tend to deal with this in a good, cheap, easy manor so that I don't put my friends out at all. I want it kept to the KISS process the SAGA system is so fond of.
Web cam and mic is probably all that is needed but quality of web cam and mic will make a huge impact on game play if they are crappy and I can't see the board.
Gamer nation what do you do and what you suggest for this?
Sex in advance.
