Fastest way to exchange fiat for BTC?

[GuiltySpark343]

In researching BTC exchanges, it seems like a transfer of fiat from a traditional bank to Dwolla takes 3-4 business days, way too long. Other than their "FiSync" network, which provides instant transfers but requires an institution to use that interface. Currently, I believe there is only one FiSync bank participating.

Any other options that are faster for getting fiat into an exchange, and ultimately buying BTC?
