Should I buy?

If you were going to make nurturing back to health a project, I'd say go for it. But not for 100 bucks.

Yeah that’s what I’m thinking

what do purple tangs go for anyway?

But you are looking at putting an unhealthy fish into your display. I'd resist the urge.

If I got it, the fish would go into a 14g qt tank with plenty or grazing rock

I would pass on it passed on your situation and the tank it would be going into

For the grazing rock, should it have long strands of GHA on it?

No. Just good seasoned rock. They'll pick away at it all day long. You need not see the algae growing for the tangs to be doing their job, if you see them picking at your LR they are doing just that.
