Garth,
Depending on how much you want to trick your model out, personally, I prefer the Trumpeter 1/350 USS England. The molding is nicely crisp and very little flash. Gold Medal makes a PE set for her and Master Model makes barrels for the 3/50 in, the 1.1 and makes a complete set of 20mm guns that are tricky at first to build but make into an amazing representation with round barrels.
At this scale the length is 10.5 inches long and 1.25 inches tall.
You can get all these on evilBay.
