Hey, I've decided to start a project with my '98 Civic, and I think the first place for me to start is adding a remote start/keyless entry/alarm system. This will get me something I've been wanting for a long time, and get me more familiar with my car's innards.
Reading this forum, it seems DEI is the official r/s/alarm company here.

That means my list of products boils down to basically the Viper 560XV or Hornet 563T (basically the same, I understand).
Now my problem is, I've found WAY too many online stores selling these things, at wildly varying prices, from $50 to $500. It seems $125 is about the average price.
My question is, what online stores are reliable? What stores have you all used? There's always ebay, but it doesn't seem like there's much on there, not to mention the high possibility of buying fake or crappy products. Thanks for any suggestions!
