As you can clearly see from the graphic [right] there are five basic ways that an Investor can inject funds into your firm's balance sheet.
A quick analysis shows that either money from an Equity Fund or Venture Capital are clearly the worst because of time, risk, etc.
Equity + Debt and Debt Funding are viable alternatives but you can clearly see that the absolute best funding alternative/source is Straight Equity via a Super Angel. It scores the highest score  because it is fast, viable, low risk and has the overall lowest cost to acquire.
Straight Equity has other advantages that are not reflected in this chart:
1. No Payoff [i.e. you don't pay back the funding.
2. It can often include a Buy Back Offer, allowing you to pay off the Investor at a defined date - 3-5 years.
3. Oftentimes it can also include a delay of up to two quarters before equity-based payments are made.
