Tranfers to MtGox via redeemable USD code (do NOT exchange to BTC, huge fees on Bitcoinica for that). Link up Dwolla to MtGox. Transfer USD from MtGox to Dwolla. Link up checking account to Dwolla. Transfer USD from Dwolla to checking account for 25cent fee.
If you don't already have all those accounts set up and linked it is going to take you a while, at least a week, to complete the process. See how easy Bitcoin is!!! /sarcasm
Thanks, looks like I picked the right places, I'll finally get to use the Dwolla account for something.
