It a bot disingenuous to advertise 85GH units as 110 in the title. Just because it can be theoretically overclocked to there, with voiding the warranty, aggressive cooling and a dramatic increase in error rates, does not mean it should be advertised as stock speed.
Now, if you were to pre-overclocked them, provide the cooling solution and guarantee the error rate from your own testing, then it would be a fair advertisement. Regardless, if you serious about moving these, 1BTC per gigahash at stock speeds is what is fair and would offer a decent shot at a ROI for prospective miners. I think you will fail to find buyers above the 85-90 BTC range.
Its the same cooling and power solutions as stock. I'm advertising the same way everyone else is.
