keep in mind:
MiniDV cameras are garbage in inclement weather (ie. skiing). Expect to lose a bunch of tapes because of moisture/extreme temperatures.
VX's run at a premium in the sd game. You're looking at spending $700+ for a 20 year old USED camera (easily $1300 with a Mk1) Also, everyone who has ever touched that VX is a dirtbag skateboarder/snowboarder just like you so that camera is not in mint condition, despite what anyone says lol.
DVX/GL is a more affordable option if you still wanna film SD.
Tbh filming skiing with miniDV sucks. Try to imagine the feeling of losing a tape (60 minutes of footage). After you've imagined that, imagine losing 10 tapes worth of footage. If you think you can handle that kind of despair, then go ahead and film skiing with a VX. Not even the VX god Beagle himself films with a VX anymore.
Just buy an HVX200 (should be able to find one around $450) I promise you it will be better. you can still film 4:3 SD with miniDV if you want. And you have the option of shooting HD.
Just my opinion though do whatever you want i dont care
