before I'd start more paysites I'd build huge amounts of traffic in the niche so I can live very well of my own traffic
I can not recommend anything else
as far as the 100 grand goes... I had the same question come to my mind a few days ago
I wanted to go with mainstream but then the question... where to go? where to find people selling their mainstream sites´.... and then I was lost
I am missing resources here
if anyone thinks he can help me here with urls and such please mail me. people who help me never regret having done so
oh... as far as investment goes... I put $40k on a certificate that I think is going to make me a lot of money in the next year (and secure either

)... you might want to look into that market as well...
