It's up to you man and it depends if you are able to sit there and watch the stock or not.
If you can watch it, wait for the first dip, then gobble the crap out of some cheapies. You have to be very quick though as any dips should get taken back up very quick.
If you can't watch it, put a limit in for what you are comfortable. I would say .007 will get it done at open. But you can check what the bid ask is before market open.
