Power Tap

 My daughter just decided to not try out for Minnesota Junior Elite Triathletes because the coaching group she used last year is now charging a fee equal to the cost of a power tap and after watching me over the past few weeks...she is sold on the advantages of the power tap.  Having said that, does anyone out there have a power tap for sale?  She is only 17 so it would have to be affordable.....anyway, checking e-bay and Craig's list but thought I would start here.  Thanks!!
