i just bought the viper 800. it was a great story too. i went to circuit city yest and was going to buy the viper 600, but when i looked at the board it was on, it said that the viper 800 was only $280 and the 600 was $350. i was just going to leave because the guy was busy but i knew something was wrong. so i told him i wanted the 800 and when he was putting it in the computer he called his boss over and to my prevail............
i got the viper 800 for $280 instead of the price it should have been, $470.
haha at least something worked out for me.
anyway the 800 has every option imaginable, it even has the optional pager too. if you have the money i would say get a viper.
