With that budget, I'd go for the Nextbase 522GW or Garmin 66W. I'll link to our review of both below. However, a mid-range dash camera (Nextbase 322GW, for example) might be worth looking at if you don't fancy all the extras that top of the line cams offer, but you still want great footage quality. I'd mostly look out for Parking Mode, high-quality footage (above 1080P) and one that has time, date and speed stamping so you can use it as evidence if you need it for an insurance claim. Nextbase's cameras offer all these things.
