Hi all - fairly new to the hobby. I've got only three GAW fury miners at 1.44 MHz/s is the Gridseed faster than these? From what I've read, I thought that they're only good for litecoin mining and are 300KH/s. I also read that they're 8GH/s. So, not really sure?? 

So, if that's the case, then what is the next (reasonable) step up from this - I'm looking for something inexpensive, and no don't suggest an ANT miner. I'm not forking out or even considering something that's $2k.

Thanks
