All the DT's I've preferred on the Nuppin have been salvaged from other atties (serpent mini is my fav recycled DT) or made by hand (thanks to another ecf'er). Careful of the metal drip tips, when doing a Mundy coil (centered above the center post) the coil is a gnats eyelash away from the drip tip which is a short if it touches (thanks Reo spring for helping me figure that one out) JKM tips also work but are kinda spendy.
