I bought mine at Sams. $78.99 each, which is not bad at all.Was really happy with the performance. Cant run past 80% or so yet, waiting on my 60a circuit breaker to show up on Friday. Ran 80% for several minutes today moving quickly from one point to another. Running a solid 3.0 mph in my classic (80# MK maxxum pro). Works for me.2008 Pantera Classic2014 Mercury Pro XS 200
