If you want something excellent, Tori Richard Honolulu.
If you want a bargain but still pretty high quality, there are TONS of Tommy Bahama very gently used on eBay.
If you want medium quality at a lower price, Yiume.
We used to like Pineapple Boutique near Aulani but on our last trip they had almost zero selection for men.
I don't like Reyn Spooner because their sizing is poor. The classic fit is too short and boxy while the tailored fit is too slim and long. Also (TMI) the "Spooner Kloth" material chafes my nipples.
