i just got a Transcend 200 works well, has 160deg view
came with a big memory card has all the usual stuff but also has its own wifi so you can stream and downloand to your phone and setting on the phone.
has no battery so has to be plugged in but not a drama. uses a long live capacitor to save settings ect.
also has no gps which is a plus. the gps are often inaccurate so you can be left with an overlay of incorrect speeds which can read to high or read that your mocing when your stopped. these can become legal issues.
