I like the Smiling Shark SS-5039, even in stock form, because the shape and finish feel good in the hand and look good. The 3W is a joke, but output is OK.
SK-68s would be the usual choice and very good. The cheaper ones tend to have poor tail threads. UltraOKs, from Richard, are consistent quality, but around $5. I like SK-58s better, but they tend to cost more and have a bit less output.
I don’t like the little #3 zoomy, esthetically. They are very practical and cheap though.
