No one is selling for 2-3 LOL. I'm selling for 1.1.

That was not aimed at you dogie!

However, it only 1.1 based on the theoretical overclock speed. You should price on guaranteed stock speed. At 85 Gigahash, X 1.1 would be 93.5BTC and X 1.8 would be 153BTC.

I believe you are asking 120BTC which would be 120/85 = 1.41BTC per Ghz which is a likely loss. I think 1BTC per GHZ is about where breakeven with +/- depending on wattage cost. Now, if you pre-overclocked it, flashed the firmware, gave the appropriate cooling solution for it to be stable at the OC'd speed - then you could claim to be selling at 1.1

Show me a B2/B3 that can't run at 105+.

I haven't had any luck getting mine above 85. Even with a new power supply and AC being pumped right into the inlets once I try anything above 352 MH/z clock my error rate begins to soar. What tricks do you use to get it above 100??

By that logic any device can be overclocked including USB block eruptions so the oricing logic based on stock speed holds true. I know 450-500 mega has is possible with them with significant cooling (though warran voided its firmware flash). However, it does become less efficient per megahash as errors increase. A 10% increase in speed with a 100% increase in errors, may not be a good trade off.

Currently, you can buy 334Megahash USB block eruptors for 0.6 BTC each (https://www.btcguild.com/index.php?page=store). There will never make a profit, however I actually bought 3 simply to do my part to help distribute the network. This equates to 1.8 BTC per Gigahash. This is a 100% losing proposition with the current rate of difficulty increases. It MIGHT be possible to break even with some aggressive overclocking and some luck.

People are trying to sell Avalon and CFL units here for the equivalent of 2-3 BTC per Gigahash. Even if you just want to do your bit to help distribute the network, you be better off with the block eruptors. They are more power efficient, are far more modular, much easier to resell and easy to overclock with some cooling. All these units are rapidly depreciaiting in value. It will not be long before the only units worth buying are measured in Terahashs/second as opposed to Gigahash - also power efficiency and overclockabiltiy will be king to be able to turn a profit.

My advise, if you want to mine for a profit, buy some ASICMiner or take a risk on one of the IPOs (most of which will wind up being scams like BTCGarden btw).
