Homepokertourney.com is indeed a good site. There is also a forum just for home games on here. (

One thing to consider before doing a rebuy/add-on tourney is that it takes more time because there are more chips in play relative to the blind structure. Also, If you have unlimited rebuys, you're practically ensuring that everyone will be there until the rebuy/add-on period is over - so add that time on also.
After that, I think it's just personal preference. I personally love rebuy tournaments because it increases the prize pool so much, but you'll find some people who can't stand them.
