You want a drone with a real 4K camera that will last you a few years instead of breaking on flight three. Buying quality once means you skip the cheap upgrade cycle and actually get footage you can use.
Timing matters just as much as the model you pick. Wait for Black Friday sales or watch for the exact week a newer version gets announced so you can grab last year's top tier drone on clearance.
That intro window is a hard deadline, not free money. If you still have a balance left when those 18 months are up, deferred interest will hit you hard on what is left.
