I am one of the many it seems on this website with a running related injury (in my case achilles tendonitis), and am considering going to a water running program for a period of time. But being a tight-a_ _ , I cannot bring myself to pay $50 for a belt I'll only use temporarily. Do you know of a cheaper version of the AquaJogger, or something similar? Also, my pool is closing this summer for repairs/improvements, but I assume there is no difference if I do these workouts in a lake, correct?

Thanks!
