TB,
Start saving your "bit" coins. (Is that Coins with teeth-marks or Byte marks?)
As Stikpusher said, the USS Houston is available in 1/350:

It works out to $234 plus shipping.
If you really want to try a "Houston" 1/700, I have a USS Chester (Northhampton class CA), in resin somewhere. I got it as part of a "lot" purchase. I recall it had some painting done and is missing some parts but hull and most of the superstructure as well as turrets are there. PM or email me.
