avital 5303, prestige aps920, or aps 997a

I'm looking to get a new alarm. Out of the three, I've installed a handful of the APS-997a's, and I like them, but I'm interested in the newer ones and they're all the same price range. What do you guys here think would be the best choice out of the three?

I agree with lectricguy. The Avital 5303 uses what I call DEI's "spaghetti system." It's an antiquated idea that no other company uses anymore---the brain and relays are two separate pieces, so it takes twice as long to bench-prep, and still comes out looking like a big mess anyway. There are some installers who still prefer the separate relay pack and will disagree with me. Audiovox is my favorite, and what I've been using for the last nine years. The APS620 and APS920 units are clearly not as well-made as the regular Audiovox product, and only have basic features.....lectricguy already did a perfect job of explaining the differences. 920 certainly should be cheaper than the 997 by quite a few bucks. If you're finding both of them for the same price, the 997 is definitely better. If you're willing to spend a little more money for better range, look for the Prestige XR9000. It has pretty much the same features as the 997, but with slightly nicer-looking remotes, and far greater range.

Thanks for the help guys. I've always liked the aps-997 and you've basically just confirmed what I thought about it. It's good and I should keep using it.
