I would love to get a vacuum chamber thing for him but there are a lot of different ones out there. Any advice or suggestions would be so helpful. Running out of time and dont want to get the wrong thing. This is just a hobby for him but hes mentioned this several times so i know he would be happy with one he made himself but i dont want him to have to make one (he made most of his own equipment so far) or get him a junk one. Not knowing where to turn, im hoping someone can help. Please
