I need to buy some turnkey wordpress websites for a few different niches - I am looking for sites like this one: http://flippa.com/auctions/2671139/site .

The niches I am looking for are:
- Weddings
- Extreme sports / Activities
- Events (Event Planning / Event Venues)
- General Travel / Adventure Travel

Have you got any suggestions as to the best place to look for them ? - other than Flippa
