Poll: to js or not to js?

Actually the question is not whether I should use javascript, but whether I should actually spend the time and effort making the application work without it. I want to be considerate of the blind, but on the otherhand I'm not sure if I'm putting too much effort into that. Maybe I should build the ajax version first, launch, and then start building a verion that works without. I use noscript but have a liberal allow at first loss of functionality policy.

note: I really think the non-js version of my site is going to be cludgy

so how important is having a non-js version to you?
