Products similar to Trigger Point

Id love to get the actual trigger point lower leg kit, but im a broke college student and its out of my price range right now. Anyone know of any similar products that are meant to do the same thing?

You can get a foam roller for about $10-15. Use that for hammy, glut, quads.

Get a handball (not a racketball) for a few bucks. Use that in lieu of the TP ball.

Got to Home Depo, Lowes, etc., get a large diameter wood dowel, get some thin (both in width and thickness) and wrap around the dowel, making it thicker in the middle and thinner on the ends. Use electric tape at both ends. Use that in lieu of the roller.

rolling pin and baseball.
