What is the least Expensive ADS Device?

Iam going to order an ADS device for the hell of it, and combine it with the newbie program, and hope for gains, i will only measure once a month and not expect much, im just curious at the success rates of ADS devices, and i would like to know which one is the cheapest to order

The cheapest one is the one you build yourself. I purchased a manufactured one and realized there was really nothing to it and then built my own which fit me much better. I recommend the vacuum type of ads. The worst part about building these is making the silicone sleeves and constriction sleeves, but if you follow this thread it makes it pretty easy.

Hats off to tps for the guide.
