Where can I find good case window molding @ a reasonable cost?

[killmeplease]

I'd like to find the type with the locking strip. I need about 10'. I'll buy the plexi to accomodate the molding.

Any help would be appreciated.

I like this vendor though it may not be the cheapest, be sure to check the window kits Case Etc
