Yeah read about the pre-order horror stories. I bought what was in stock and could be delivered right away. I don't think I would ever do a pre-order. It would have been nice to start mining a couple years ago, but its not too bad mining different alt coins and trading for BTC.
Can you give us suggestions what is the best miner available now? I'm also interested in mining.
I believe there is none, but the best way to profitable might be just buying Bitcoin and keep.
That seems about right. I didnt start for the profit. Im not running a mining farm so I dont notice the increase in electricity. Computer is always on anyway. Its a great learning experience for me so I dont mind investing some money for not much return. Some people spend 1000's on video games and dont get ROI.
