HemiSync vs. Sacred Acoustics vs. BrainSync vs. Freddy vs. Jason vs. Alien vs. Predator

I know there was an earlier thread on YouTube videos with isochronic beats to induce lucid dreaming and whatnot, but in this thread I wanted to focus on-- for lack of a better term-- established meditations like HemiSync. I downloaded the free sample from Sacred Acoustics, and there are times when I listen to it that I get this tingling throughout my body, which I take as pointing me in the right direction. However, I don't have the money to purchase these tracks on whimsy, and I'm working on setting a daily meditative practice. Do any of y'all here have experience with such tracks, and what are your recommendations?
