Question : Craigslist software clone

I am looking fo software for my website that has the flagging features of craigslist.

I spent the weekend searching the web, and although there are hundreds of bbs and classifieds programs (some which even claim to be clones of craigs list) only one that I found actually had the flagging feature. (LocazoList)   There is also AJ Classified Pro which claims to be a craigslist clone, but it costs $150-200

The LocazoList software is written in asp, and I would prefer php or perl.

Anybody got any ideas?

Thanks!
