I've test ridden the Coda Sport and was very impressed by the way it handled and otherwise performed. Ended up buying the Coda Elite, which is simply a great hybrid in my book. Test drove a few others and wasn't as impressed. However, I never rode a Kona, so I can't offer any opinion there. I've heard great things about that company as well, so hopefully I'll be able to give one a spin someday.
I own the Dew Deluxe. AWESOME bike! I modified mine with road bars, and later moustache bars, but the bike is well-made with quality components from the factory. IMHO, you can't beat Kona for the $$$. Happy shopping!
