If you are looking to use a bank like how Kit and Pierogi and myself do, then check out SinisterSpatula who has a chrome extension that when set up lets you spoof the real BoA or DATCU credit union, and some other cool things like redeeming GooglePlay cards, a bitcoin wallet, PayPal account and much more. It is super easy to set up and there is a trial but its so easy and fun to use when scambaiting that its worth paying for.
