max 300btc if you want any kind of ROI on this
If looking JUST at BTC returns perhaps...
What other returns are you looking at? Serious question.
If you mean merge mining with Namecoin, I didn't think that was especially profitable. Are there any other uses for an ASIC miner like this or an Avalon when they're no longer BTC-profitable?

300 coins is $30K more or less (today)
If you mine and keep all coins and in 1 year you have 300 coins and that is worth $90,000. A very handsome return....
