One thing I forgot to mention; if you do opt to go with the MBW case, you'll need to mod the case slightly. Lugs need to be drilled to accept gen springbars and the CG's will need to be shaped for best results. Granted, the Yuki case could probably benefit a bit from CG shaping as well...
$700 for a case, dial, hands, Tudor rotor and gen crown and tube is actually not terribly bad. Just add a movement. If you are using a Yuki supplied case, and they are able to provide you with a blue insert of the same quality as their black 5513/1680/1665 insert, you'll be in good shape.
