Take your pick....it depends upon your skill level, and the level of detail you want.
Eduard - great set, lots of unusual parts like deck gratings, but done in stainless so a bit tougher to work with.
White Ensign - incredible set, but very fragile, not recommended for the beginner. A bit pricey too.
Gold Medal - great set, perfect for the person who wants details but isn't an expert in PE. Reasonably priced.
Tom's Modelworks - very affordable set, perfect for the novice or inexperienced modeler, or someone who's reluctant to pay more for the PE than he is for the kit itself.
You can see scans of all of these frets except Eduard, on www.modelwarships.com in the review section.
