Just curious as to your needs for the hardtop? Do you feel its a necessity, or do you like the look?
I've never had a hard top and have run a soft top (or no top) for the last 6 years. Winters in Iowa were much more severe than here in CO, and I personally never once wished I had a hard top.
Suppose if I had one, I might run it periodically, but I really enjoy the flexibility of a soft top so much more.
Regardless, good luck on your search. I've seen them on CL in both the Denver and Boulder area.
