Am I out of my mind?

I just bought a Z2 4 string off the Evil Bay. It is not anywhere near as fancy as some that I've seen going out the door lately. And clearly it's somewhat vintage given the Barts. It doesn't even have the "D" decal on the head stock.
A few pics:

Looks like Serial No. 5016. Anybody know how old it is?
Looks like a Pau Ferro board, but hard to tell for sure.
And I know, it's only a 4 string, but I love my ABII-5 with the FD1s in it and the mahogany body. So I wanted something different (no competition) and I wanted a four banger for slapping and for a bit more ease of getting around on it while singing.
I recently bought an ABI-4 in WPB which is a very nice bass, but when I saw this, I couldn't help but think, here's my chance to move up in the world for what seemed like a reasonable price. Lord knows I am a long ways off from affording some of those masterpieces I've seen on this board lately!!
So here is the linky: [url:3tbawhs8]http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=ADME:B:EOIBSAA:US:11&Item=230245846726[/url:3tbawhs8]
Did I pay too much? Did I do OK? I figure I can upgrade the PUPS to Mach 3s down the road.
I just couldn't help but think if I didn't pull the trigger and go for it, somebody was going to (probably Fullie!

).
If I like this as much as I think I will, I can always sell the ABI, as it is in virtually new condition. I'd love to keep them both, but I don't think I can afford to.
OK, I am now officially in need of rehab!
