Mmm... It looks like the Crimestopper CS2011 IV might be the way to go... Its got the alarm, the remote start (w/ diesel features), and the keyless entry, for less than 100$. I'm seein' 85$ at retail shops, and as low as 77$ 'buy it now' on Ebay.
Sounds like fun, might be a good x-mas present.
Of course, I'd still need an actuator for the door to use the keyless entry, but the remote start could be nice on the cold winter days...
peace,
