Both 4mm bullets and andersons work fine for 30 amps IMO. Both have differing advantages and disadvantages. If you prefer a crimp to a solder, go andersons.
But for a bit more than 40 amps, the 4mm bullets can carry more current, and work good with larger than 12g wire. 5 mm bullets for 8 g wire.
There may be hobby stores in Israel that have bullets, but many of us just get them from HK.
actually my current phase connectors i'm using (and that haven't melted) are in fact http://www.molex.com/molex/products/datasheet.jsp?part=active/0428150012_CRIMP_TERMINALS.xml cause it came with ecospeed and i'm guessing they had a reason to use it, i'm currently in the process of finding an spare motor, as well as ordering from ecospeed another motor (once they get them).
