For me it was simply the 3K for the upgrade (Zo, ECM, Malibu Harness) I didnt WANT to spend the money... ZO could have really helped and still could help themselves by offering an exchange program on the ECM's. Not sure its possible or feasible, they may not even care since they kind of have the market cornered at this point being its the "Approved" system.
One thing I would like to add as a side note that may or may not sit well with some of you and I apologize if it doesnt but anyone who has been in this sport for more than a minute or two knows how much skis, ropes, gloves, etc cost... We aslo know how much boats cost (generally speaking). Its not rocket science to research and figure out what it would take a person to build and maintain a Private site. That being said, I dont give a crap if you make 500k or or just filed bankrupt, if you want to ski and can pull your weight, lets go! If a person thinks another cant figure out within a few thousand dollars what you have into your setup your sadly mistaken. I have noticed on multiple threads reference to costs and just to remind or enlighten, money doesnt make you cool its invites false friends and puts you in a different tax bracket! I hope noone takes this personal, its just a prespective I have, its not like car or motorcycle racing where you can mod and mod and keep modding until you have tons of cash into a car or bike... Generally speaking!
