Just spotted the link you posted Nino.. have seen these before, they look ok but don't have the resonator box the originals had, don't know how much that would affect the sound though. Actually looking at them again the way they are constructed they look like something i could almost make myself.. not that i'm going to that trouble for this Jet Spin as its really rough cosmetically and wouldn't be worth the effort or time, and this guy its his first machine and just wants it to work and play good, he's not worried about cosmetic condition.
