About 4 years ago I rode while in Cancun at waterskicancun.com. I believe the guys name was Scott, and he was exceptionally nice and professional. I emailed him before I left and he was quick to hit me back and answer all my questions.
I don't recall exactly which year and model they had but it was a newer V-Drive Supra with full ballast. It was having starter issues the day I went over. Frederico was the wakeboard guy and he let me ride that day behind some boat with an OK wake, which also had some mechanical issues, but they told me I could come back the next day for no extra charge and hang out and ride. When I showed up I was kinda just like crew and took just sets between the folks that had scheduled times. In total I gave them $80 and a $30 tip, for about 4 1/2 hours on the boat in some very decent conditions. I just can't remember all the details and prices, but I had a lot of fun, and luckily got in plenty of riding for what I paid.
