I would go with 2 Westinghouse i4500 with a 50 amp parallel cord. We have two of their i2500 and they are strong and quiet with good fuel mileage. Two i4500 will provide all the juice you need and at times you will want to run only one.
You can get 50A out of two iGen4500 but only at 120V ! That means only ONE A/C unit !
If you are willing to have an electrician do some wiring, you can change you 50A plug to two 30A plugs. You will need a second breaker panel installed and you won't be able to run any 240V appliances.
