You have some choices based on what kind of modeler you are and how much detail you want to add to your kit...
If you want an inexpensive, basic set with rails and all the other necessary parts, get the Tom's Modelworks set.
If you're looking for superdetailing and every concievable part you can think of, get the White Ensign Ultimate set. But they're more expensive and fragile than the rest.
If you're middle of the road, get the Gold Medal set.
I would suggest taking a look at the reviews of all three sets on www.modelwarships.com , we have scans of the frets included.
