I guess I'd probably go collectible. I'd like an early powder blue standard.

I lean toward collectable ones myself. My '88 Sig sounds better to me than any other PRS I have played and while I have compared it with a few PS I have never played a collection so what do I know? To me there really can be something magic about an older guitar. Not to knock the new ones but when I play the right older guitar I tend to bond with it well.

I'd go Collection guitar. I'm not generally a fan of older things, plus I love pernambuco necks, nitro finishes and the latest 'tweaks'.
I think the newer "collectible" PRSi like the Modern Eagle, Paul's 28, and Collection series are all fantastic guitars. That being said, there's something about an old Vintage Yellow '85-'87 with birds, an '86-'88 Signature, or a Dragon I-III. An '85-'87 Pearl White, Baby Blue, or Silver Pearl Standard is nice, too. I like 'em all!
