J is right, Gemlite's Sandalwood provides the best bang for the buck around. I really think anyone who is interested in a sandalwood FO should at least check this out.
Otherwise their FO's are pretty hit or miss. I really like their Tangerine EO (in body products, not anything lye related, no scent retention there), their Lavendar FO (mild, good floral/herbal, widely appealing blend to those who like lavendar) and a couple of others.
They do offer cheap samplers, though (in v. small, pretty glass bottles, I always wonder about this, they must be expensive) so you can check them out easily if you are willing to do single bar samples. And the owner, Robin, is very nice and easy to work with.
