Replying to Alpha 2 Debate

Alright, so I'm planning on getting either the Alpha 1's or Alpha 2's sometime soon, but I found a real deal on a demo pair of Alpha 2s at a ski shop. They are a bit beat up, and have pretty heavy rental bindings mounted on em. The good thing is that I can probably get them for 20% off the usual ($550) including the rental bindings. My parents are all for buying these ones since its a great deal, but I'm still undecided seeing that they are in alright condition, and I don't really like the bindings. So, should I buy the used pair, or splurge the extra couple hundred bucks for a brand new pair with bindings of my choice?
