MA1 batteries are obsolete, and no aftermarket ones available as far as I am aware . . . that’s one important consideration.
Lightly used might mean the package sat around unused for long periods, and that can lead to damaged batteries if they depleted too far in voltage.
Make sure flymore batts are
A1, reasonably low charge cycle counts, cells all ok and balance fine when charged.
Another is
MA1 is wifi and a little less range, though my brother in-laws regularly got him well out to VLOS range in good signal LOS situations.
If choice is
MA1 or
Air 2, spend the extra $170, again extra care with battery condition, a test flight and check if those is a great idea for 2nd hand if possible to buy local.
The
Air 2 is a fine aircraft, but as long as you watch maximum wind speeds, have you considered the
Mini 2 ?
This is probably equal to many aspects of the
Air 2, no obstacle avoidance, but similar camera output, and same excellent flight stability etc.
An excellent starting drone, and you might even find a brand new flymore package is at a reasonable cost too.
