A MW is named for its output cooking power, but it sucks way more than that for input power (the inverter has to supply that) Look at the label on the back for what your input watts is. Eg, a 700w will want 1050w in. An 1100 will want about 1500 in.
There are many inverter brands and some have a bad reputation. Price is not everything for quality either. I would choose a known good one even if it costs a bit more. Some that cost more are not the good ones. Sorry can't help with choices. I can say the PowerMax one is good based on using it for a couple years now, but it does not have the remote display you want. (I don't know what good that would be in real life if you already have a Trimetric monitor) A remote on/off switch is very good to have though.
