Maybe I missed this, was there noted damage on the shipping container/crate, cheap as it may have been?
If there was and you didn't note it with the shipper it may be your only offer. If the carton was intact, then it wasn't shipping damage, and they crated up, and sent you a damaged item, so return should be on them. Being a gambling Man I'd say either 200 bux, or come pick it up.
Running smooth as silk, or not, if you ever decide to upgrade to a bigger jointer, or just swap it for something else, you are going to take a butt thrashing trying to sell it, and a can of spray paint ain't gonna cut it.
I also wonder why it is they can't send a replacement if it was just in their lineup. That sends a bad message about Griz/Shop Fox, not having spares at least for a while after being in the lineup.
If you aren't happy, and I am sensing you are not, seeing that you came here, and asked what should you do twice now. First after noting the problem, second after that insulting offer. I may not know everything about Grizzly, but from being online for a lot of years at woodworking forums, I do know they oil squeaky wheels. I'd be making more noise.
