nothing compares to advertising in members areas
if you have ever ran a tgp or advertised on a tgp, then take the conversion rate you got from that tgp and split it in half
any time I see tgp guys talk about their conversions it is usually double what I am getting on blogs, but you also have to think about the fact that since blogging is all SE related, the traffic is usually way less than a tgp....so, start lots of blogs
