Simondo has a good list going, for shapes I'd add:
Joe Bark Paddleboards -
www.joebark.com/boards - Not sure how easy/expensive it is to get his 14' over here, it's a nice looking board though.
Deep Surfboards QL - the new 14' they did looks nice
Paddle Surf Hawaii have a 14' from the sound of it - not sure when it hits our shores
Most people, shapers and shops are willing to let you have a go on their boards I'd try a displacement and a "surf" style (flat bottom) board to see if you like one over the other.
One thing I had a hard time deciding on is Custom v Production. Other than price production is nice because you can pretty much walk out with a board. The nice thing about a custom is you can tweak it to incorperate things you'd like to have and to suit your body type if you don't quite fit the "average", the down side is it can be between 3-5 weeks to get a board depending on where you live in respect to the shaper.
