Carl,

Congrats on resolution, finally. I would keep the Dolphin for sure, and either keep the BD or sell it on Ebay. Even if you lose $200 on the BD, it would be like paying $200 for a brand new Dolphin, that you don't have to remove ladders to use. Plus, you can bet if you have an issue with your new Dolphin, they will undoubtedly remember who you are and make sure you are taken care of promptly. Just remember, the squeaking wheel gets the grease.
