Well here is what my parents were told when I was in them (btw I was in braces for 4 years and it was $4,500)
"Clear" braces are ceramic and should not be used on any of the bottom teeth. They can and most likely will damage the enamel of any tooth they rub against. They also tend to have to be in the braces longer because the ceramic brackets cannot handle as much tightening stress as the metal brackets can.
Price depends not only on the actual "equipment" but as to how long the patient will need to be in them.
Sounds like a typical price and as long as you are happy with the orthodontist I would stick with them.
