I think first you should figure out your needs more precisely.
There is big difference between 500 and 1000W class inverters.
Than how critical is pure sine?
Even if you find one without remote, adding 100 amp relay and remote switch is not a big deal.
I think it might be actually better this way. My 1700W inverter has remote, has switch on it, yet when I hook up the cable with everything off, I am getting big spark.
The inverter is having big capacitor on it, that is before the relay. My meter shows no other draw after first spark, but it has to draw milivolts to keep capacitor charged.
