I agree with Rob472 that you can make a really nice site with MySpace. Just check out this one for travelocity: http://www.myspace.com/roaminggnome However, I do not think that just putting a couple of affiliate banners there will work for you.
Besides, the increasing number of MySpace members, leads to an increase in bandwidth used, which slows down the servers and may result in a “Server Too Busy” error message for some users who are on at peak hours. It happens very often throughout the day.
