I agree that stainless steel is bad for coffee (glass-vacuum carafes are cheap and effective), but it usually takes awhile, an hour or more, before I notice a significant change in flavor from exposure to steel. On the rare occasion that I cannot avoid using a travel mug, I use this thermos tumbler.
Braces cost is around $4000-$6000. Braces cost $3,000-$10,000 depending on location and also on what kind of dentist does them, general dentist (cheaper) or orthodontist (more expensive). In European countries Braces usually cost about $5,000 nowadays.
Getting braces, even traditional metal braces, isn't cheap. The initial cost for ceramic braces ranges from $2,000 - $8,500, which is close to the range for metal braces ($3,000-$7,350). However, they can break more easily. Ceramic braces work the same way as regular braces, but they are made of different materials.
