As I budget for upcoming equipment, I have a tough choice to make. The choice is between an ozone machine and a PTG. What would you choose?
PTG would get my vote too. Ozone machines can normally be found at janitorial supply houses for rent when you come across a vehicle that would benefit from its effects.
I'd say it depends on the type of clientele you're aiming for but if you're looking for a blanket decision, I would go with the PTG like everyone suggested.
