The low cost of a cheapo 1500W unit at under $200 makes it a good choice for many.
However IF I were spending those big bucks for a "better" unit the one feature that would make it worthwhile is the amp limiting/following and amp infill ability.
The ability to start an air cond on a crap 15A circuit or a second AC on a 30A power hose , or use a small noisemaker and be able to start big induction loads would be worth the extra price.
Otherwise why bother with a big dumb inverter?
