Hey Dan and welcome to the saltier side - Model Shipwrights!  
 
 Personally, I like 1/700 scale.  The price is right - anywhere from $20 - $35 USD for battleships.  1/700 is also good for limited display space.  As far as manufactures, There's a host of good kits - Tamiya, Trumpeter, Hasegawa, Fujimi, Dragon & Midship Models to name a few.
Now, if money and space are not an issue, or you just have to have it, the 1/350 scale is booming with Trumpeter leading the way.  They have an awesome selection of WW2 US carriers and are now getting in to the battleships with the North Carolina and the HMS Hood.  Tamiya is kind of the bench mark (Trumpeter is blowing them away) and Hasegawa is a new player with some nice kits.
I haven't even started with resin ($$$) and Revell's 1/72 submarines (I have 2).
Basically,  price and scale are a personal preference.  And, if you see a kit and have a question about it, these are the guys to ask.  If it's been made, they've built it.
