yup its among the best i've ever used. I prefer bobbi brown lip
gloss to stilla.
another good lip gloss will be Chanel.
I've started using bobbi brown make up 4 years back and has never
thought of switching brand.
I am using the eye make up, foundation, loose powder and lip gloss.
As for blusher i am using chanel. Bobbi brown has got good blusher
too, just that i prefer chanel's packaging. I prefer bobbi brown
make up range to other brand because it offers a more natural look
and it is easy on the face and lasting. Hope this helps? 
As for the price... its approximately SGD$50+ +for the eye make up
and as for the foundation and loose powder its SGD$60++... that is
if i remember correctly. But that is defintely the price range.
