There's a USB-based ASIC out there for X11, spacing the maker (Pinoli or something like that?) - it's the only thing close to inexpensive available at this time.
ASIC for X11 are a NEW development, none of them have been available more than a very few months, so the prices on them are still "new user adoption" inflated.
Thanks for letting me know about this. I didn't knew that they were new on the market but I'm going to make some research about the miner that you've previously recommended me. It been quite some time since I have been away from crypto currencies, so I'll have to get up to date with the latest stuff in it. For the meantime, I'll just setup some masternodes for Dash at home. I should be able to get some good amount of Dash as rewards for setting up these nodes.
