Now, the caveats are these: this is only a snapshot in time - the fees may have changed, so always look before you leap. this is based on my research, for my shop, for my situation. If you are a high volume shop, for instance, you may encounter bigger fees than I would, or smaller transaction fees, but monthly payments.
So, this is a compiled list of fees for the small crafter business as of 2/1/12 in alphabetical order to be fair.
