Yeah, I'll do the paypal chargeback. I'll bet it either gets him motivated to let me know what's up, or Paypal pretty much doesn't recover any funds for me.
The only thing that I hate about paypal is the seller is screwed 100% of the time unless you have a delivery confirmation/tracking number. Even then, I've gotten screwed twice in the past because stupid eBayers with zero feedback decide to pull a chargeback scam with their "unconfirmed address".
