Viper 771XV or Python 871xP

I have been looking for a 2-way remote start. I would like to get 2 of them, one for my car one for my wife's. I should be able to use one remote for both cars right? I like the Viper 771XV and the Python 871XP because they do not have LCD screens which are fragile. Trouble is i cannot find a place to order one online! Any suggestions as to where I could obtain a pair of these alarms? One last thing... What exctally is the difference between the two? I dont think there is one....

 the problem with buying viper or python on line is their is no warranty and it is refurbished ..... look into BOA or hornet it is made by the same company and is just as good if your interested you can e-mail me over 20 years of experience in the 12 volt industry

I dont care about warranty What is BOA? The last one I bought was a hornet 554 from ebay and it was alright, but the shock sensor wasnt to good.

I paid like $280 for a Python 881xp at Circuit City..... The shelf price includes install.... but it can be rang up without install ....... the sheet said like $160 for install and $80 for shop costs ...... you just need to talk to the right person ...

Thx, Ill try that if I cant find it online
