I never been to this show, is it any good? Is it worth driving from the Manchester NH area?

It is held in a smaller arena.  IIRC its a hockey rink.
I've been a couple of times (Of course Keene is a little closer than Manchester).
It is a smaller venue.  some of the usual suspects.  some different.  Nothing REALLY remarkable. Kind of reminded me of the shows up in Lebanon, NH.

Is it worth it?  I don't know.  It certainly is a nice drive through some pretty country.  People up there are nice.  I'd say,  Go to see it and if you don't like it don't go next time.  Course that's only me. YMMV

17th-18th.... Same weekend as Syracuse show in NY

Used to be at the State Fairgrounds hockey rink.  Dimly lit, damp smelly pit!  Now it's at the Holiday Inn on Rte.7 south of town.  Slightly more tables than Lebanon.  The guy I help out usually does well at it.  Manchester, NH is coming up in a month, though with its usual size and venue.
