Simon, don't continue, i am pretty sure people/entities like me and Murat aren't offering anything there but those with 100+ of /24. And who have the loudest tone against the policy charged by resource holders! And regarding such sites, you would encour alot of issues i.e last time we got a /24 from one of such sites will not name it now, because abuses are unpredictable, we got our whole /24 withdrawal and leaved our existing customer all offline due for one customer who abused his IP/service. So go and do business with such sites if you dare.
