Remote starter advice

Hello all,

I'm looking at getting the DEI VAlet 561R remote starter / keyless entry installed into my 2003 Honda Civic:

The car didn't come with any type of remote entry, and since I am absolutely sure I couldn't install one on my own, I checked out the local Best Buy and Circuit City. The latter has this product, installed, for $159 which sounds very reasonable.

Unfortunately I can't seem to find any good resources for reviews or details on this product. For instance, what is the range? It says it comes with an extended antenna that will give it a 1/4th mile range, and I believe I'll need about 200 feet (I live in an apartment). Also, I assume I have to leave my AC (or heat) on when I turn off the car, so that when I remotely turn it on it kicks in?

they make solid products - is that true? I've heard horror stories about cars randomly starting on their own, and obviously I'd like to avoid that.

If this particular model isn't good, any other recommendations? Please keep in mind I have to have some way to have it professional installed (for a reasonable price). Thanks a lot.
