Can anyone recommend a brand for whitening teeth?

I've been wanting to whiten my teeth for awhile, but there are so many options that I don't even know where to begin. Any help is appreciated!!
--------------------
If you don't want to spend the $400 that a dentist charges, the Crest whitening trays work best, but are more expensive than strips. Using trays to whiten is more effective than strips but is also a bit more expensive. Crest white strips would be third down the list and definately work better than the dissolving ones. And, leave those whitening pens at the store. You can also dip your toothbrush in hydrogen peroxide, slightly diluted, and brush with that. Rinse, DO NOT SWALLOW. This will help whiten, too, as well as brushing with bicarbonate of soda (arm & hammer baking soda). So, SMILE,,,,, :>)
