PPC vs Buy Traffic – Which is more cost-effective?

Like many e-preneurs, I’ve lost a lot in PPC – getting less than what I’ve spent. In essence, PPC is a very expensive campaign to undertake & we could easily lost our money if we don’t know what we are doing.
As I go-&-learn in Internet business, I found out that traffic lead/buy traffic is lot cheaper & more cost effective. Plus, some traffic sellers now offering targetted traffic (geo & category). In essence, traffic lead campaign is "safe" for both beginner & expert online marketers.
Please debate – which one that you think/feel is better.
