Don't do it. I'm long NTEK though I'm too busy to post much here.
This is my opinion. Take it or leave it. NEVER, NEVER buy penny stocks with cash on hand you cannot afford to lose. And to buy penny stocks with borrowed money is as irresponsible as those financial giants that gambled with other people's money and crashed the whole country. I was in a stock not long ago and it was of course one of those "rare gems in pennyland," and several people borrowed money to buy the stock, and the whole thing went ka-blooie. People lost their arses. I lost too though I exited immediately and saved a good chunk of my investment. One guy was severely depressed. He lost big but so did many of his family and friends the he convinced to get in on the stock (including an elderly relative who is not likely to recover ever). He actually talked openly on iHub about committing suicide. Part of the discipline of investing is not letting your emotions get so carried away that you lose all perspective and make rookie risks that can blow up in your face. Just friendly word of advice.
