every fake tan iv used has a funky smell afterwards, im not keen i know they say sunbeds are bad but i would recommend a couple minutes each time over the space of a couple weeks with a high factor suncream and you should be fine, its all about being carefull! more natural too and you will still smell fresh as a daisy!
However ...
If your still stuck on the fake tan the piz buin one is a nice colour but the thing i will say about mousses its hard to see where it is youve been etc, if you want a really good finish the salons usually do a good job of it!
