I had the same problem after a caliper rebuild. You want the pistons to be pushed up tight to the pads prior to bleeding. Use a spacer thinner than the pads and pump the brakes to allow the piston to move forward a bit. Force the pads back in and bleed. Without doing this you'll never get a good pedal.

The $45 for a Motive bleeder is money well spent. I wouldn't waste any more time (and $$ Super Blue) bleeding the way you are currently doing.
