I've built a clutch of the Mirage kits and really love them. They're a bit fiddly---with lots of tiny pieces to clean up---but they're really nicely detailed, including properly cambered decks!
The old Revell war-horse is still a sentimental favorite. Nice big easy-to-work-with 1/240 scale, fair detail for its vintage. With a little love...like replacing or up-detailing guns...it can be a real dazzler.
Nice p-e sets available for both of the above. And Al Ross's Anatomy of the Ship entry on the Campbeltown is a must-have resource.
