They are amaaaaazing, rode my friends scooter last weekend with a elite deck and the elite wheels. The deck is probably the best deck i fellt, it feels like a wide thresh that is lighter. The wheels are so fucking smooth.
A canon 700d with a samyang fisheye, canon 50mm f1.8 II and a 18-55 will have you covered for a long time, message me in facebook: Love Bror Svensson if you need any more advice on what to get.
No need to get a 700d, get a 600d from ebay and you will save $$$. They have the exact same features for video. You will need to get a mic, the internal mic is horrible, get a Rode video mic pro.
You would make sure to have a lens with IS (Image stabilization ). ALso you would probably need some kind of handle. But the thing that is the most different is that you need to use manual focus.
