i'm looking now i just sold my ctx3030 "didn't live up to the Hipe " i have a v3i i love it and a excalibur for water and i love it but want something for the motorbike…. small yet powerful i think you could put the controller in a waterproof case for them rain days like three in san diego LOL i have the money just sitting in paypal waiting for some one to sell them three coils and wireless headphones set ….. soon i hope and i sure hope it lives up better than the ctx did…. i mean it worked ok but nothing like the best machine ever i read about……
