We use Sjolie with great results. We are focused on organic ingredients and like that they are paraben free.
We have used Celestial
Bronze , it lasts about 10-14 day and is pretty good color and scent.
South Seas is really nice too, a bit pricey, but it lasts about 10-12 days.
Aviva Labs seems like a great
solution , I even got a few samples. The only thing I missed in talking to them was that they are NOT paraben free, so I cannot use them, sadly.
We're still looking around.
