You could try buccaneer to build an initial model, followed by ARP/wARP
to complete the model. I've see some good results on maps in the
2.5-3.5A range with buccaneer, but model completion is still not so good
(although it gets better with each new release).

Buccaneer is particularly good on well phased maps at lower resolutions
- e.g. after averaging. With high order averaging it should be able to
build at 4.0A.
