This page has a pair for $75 without air:

but I put new seals in. I like the air, some people change the springs inside to better ones (I didn't cause I'm cheap). You might also have air leaks in the hoses to the shocks? Put some air in and spray with soapy water, look for bubbles...

is for a 1200, but is the same.

lots of threads to read about pros/cons of progressives or whatever.

Hope this helps!
