Newtonian focuser, (almost) any type

[jahnpahwa]

As title indicates , I'm after a focuser for a 12.5" dob that i picked up second hand. Tube diameter is large, 383mm, so the GSO units at andrews would need modding and the long perng units are sold out :( before i start filing or chopping into a new gso, i wonder if anyone has anything lying around? As long as its made of metal and 2" drawtube, I'll be happy. Dont mind if its super basic or... up to maybe $400 for something nice that mounts on points rather than a plate with diameter specific curve.



Current focuser is plastic and unbelievably bad.


Thanks!
