I found a used C-155 on a boat recycler site a few years ago for $75. Got it powder coated and it looked like new. Note that Bomar changed the design ever so slightly during the production run--the hinge height on the old version doesn't match the updated version. You can call them and find the model year the change occurred. Here is the contact person that knew:
