Hi,
I just wanted to drop my few lines to give you a ideal.
This is how I mine and you might find it interesting.
1st - buy your miners from the source, not ebay or amazon.
They are way to overpriced.
Get the best price from the source with a real warranty.
Sometimes the warranties will no go to the new owner.
If you borrow the money, then treat it like a business.
Figure out the payment to completely pay of the miner before the warranty is over.
If it cost $1800 with 6 month warranty - then you have 6 months to payout.
$300 per month
Now pay for your expenses.
The electric bill - can Cost you a extra $100 or more per month
Then you monthly cost is $400 $300 miner payment + $100 electric payment = $400
If you make $1200 - $400 cost = net profit of $800
Now invest this money into coins and leave them alone for 10 years.
Here is how I mine.
I mine just enough into my account in litecoins or bitcoins to make the monthly payment
and exchange everything else into other coins.
That is exactly the reason prohashing is such a great place to mine - easy to exchange into other coins.
When you use a coin exchange - To start its a 20% exchange cost plus then bidding on coins you might not get -
I might pull all my hair out awaiting.
For instance - the first week mine litecoins or bitcoins only, just enough to pay the monthly payment cost.
For the last 3 weeks invest into other coins that look good from using prohashing easy exchange options.

Now it takes Great Heart to Make The Next Step:
Pretend the coins are not there - don't think about about them - don't use the coins - keep them hidden.
Don't use them ever - leave them alone - don't even think about it. Don't tell anyone.
Wait 10 years or longer, then cash them out. Buy yourself a new house or something worth it in 10 to 20 years.
Mining is a investment like a retirement.
When you cash out the coins - you will only spend the money quickly - so save for a rainy day.
