Help me decide please, Used SVS PB12NSD or new ED A2-300?

I can get a used SVS PB12NSD that is a couple years old for about $400-$450, or I can buy a new Elemental Designs A2-300. Are the older PB12's almost as good as the ones they're selling now? Which should I choose?

Nevermind, the PB12 is sold. It probably would've been too much for my trailer anyway. LOL
