Thanks for the input, I wasn't sure if I should take the risk on a cheap one. So I guess I'll bite the bullet or I'll see if I can salvage this via warranty, unlikely as it may be. Installer is denying it was them. I could fight this, but I don't know if it's worth it.
So, to re-cap, my car is now grounded until at least Wednesday and I'm probably out an extra couple hundred on top of that. All-in-all a great experience so far.
