Had a PRO, played a lot of Premium old runs and now have a PREMIUM VAULT. Couldn't be happier....no difference at all. The Vault is a beautiful and great playing machine with zero issues at all.
I was offered a really nice HUO ACDC Premium (an old/original run) as I wanted to order the VAULT. But for a few hundred less (450) I decided I'd rather go for a brand new one instead. For me it was the most logic thing to do and I do not regret that decision at all.
