But in the end of the day, I would do it again given that I got a good deal on the parts again. As with installation, I had a friend help me for a bit. That definitely helped. Going in with minimal knowledge of how to change such a thing, it took me a saturday and sunday. About 6 hours saturday and 4-5 sunday. The biggest pain was just disconnecting some of the hoses and things like that. But it saved money so I think it was worth it for me.
