They have more money than they have good ideas. They are desperate to hear from you in you have a great idea. All the good VC s have an agreement they will sign to protect you. Just ask for it and they will trot it out and sign it. About an hour if it is a good one.
Money is money.
But the advantage of dealing with a VC is that they have many contacts in the business community that can help you. It may be a better fit for you long term. Others say that this can hurt you because venture captial firms talk to each other, and it can prevent a business from having any future chances of getting their business plan accepted. But not as much any more. Most do not talk about the deals they are working on for fear of having someone else get the deal.
