Remote starter advice

Hello all,

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

http://www.circuitcity.com/ssm/DEI-V...oductDetail.do

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?

>From what I could find searching through the newsgroups DEI sounds like
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.
