My current prestige alarm is fugging up so I'm in the market for a new alarm.. need an upgrade anyways.

In the market for an alarm/starter combo, currently looking at Compustar alarms but I'm getting confused throughout my research, Compustar hasn't updated their page much lately.

A few alarms I'm looking at are
2WFMAS
2W8000AS

2W900FMAS

What's the difference between these? I'm not even sure which remotes come with which alarm, I've looked up websites and all they do is post up two different remotes such as these




and the models aren't specified.

Thanks
