I bought a solo ad from Kirill Vasilyev for $15 for 30 clicks or $0.50 per click.
He promoted a site of mine called Simple Internet Marketing Formula which on average converts at about 33%.
I got 46 uniques (16 extra) and 20 optins for a conversion rate of 43% and a cost per subscriber of $0.75
I recommend buying a solo ad from Kirill Vasilyev.
