Clipper Recommendations- I haven't shaved since March 12 (Rona Beard)

I have a glorious red and gray beard, it is very stiff course hair. There's no way any of my disposable razors are getting through this mess.

I'm at the point of needing something for animal use, like when they shave a dog for surgery.

What am I looking at here, price-wise, for something I can just rake this off with?

I assume it's in the ~$350 range.
