Are you in the USA? $200 seems a lot. In the UK a full service from Dyson only costs about $80 and that includes parts. They visit your home and do the repair on site for this too!
I suggest you look at the Dyson website and contact them direct. They are very helpful and efficient. here is the link to their US site.

If you are not in the US, follow the link and go to the home page to chose your country at the bottom of the page. Good luck!
