We are also trying the eBay listings but have no sign-ups from there. Also the view rate is quite low, probably about 20 per offer last month.
However i'll give it some time.
We try to distinguish ourselves there by putting focus on our support service and the fact that we use real datacenters, not basements or the back room in the office.
Interestingly enough we had a question from someone which was supposed to be edgy i guess, he was like " if you are so reliable why don't you disclose your whereabouts?". So I did and I posted it on the posting page. He did not reply back, i believe he was not expecting such detailed answer
