Daniel from PlatinumPPI is a very nice guy, I bought my Mongoose M80G from him
I would say go with a Mongoose unit
You will find Daniel will recommend the M80G over the M80AU as the sensors on the M80AU sometimes goes off in heavy wind - which can be quiet annoying
The model before, M80AM is more made for convertibles so there's no point
The model before, M80G has everything you need and is much easier to install
Has all the useful features you would use - nothing useless and extra that isn't necessary
Thats the advise Daniel gave me as I was after an alarm that would do its job, nothing fancy with features I wouldn't use and also something that wouldn't be set off every 5 minutes when someones walks to close to the car or another car with a loud exhaust drove past
