I'd recommend a reputable dealer. That pretty much ensures a new, non-refurbed, device unless otherwise listed. You can also check out the For Sale section on this site and find a few, but much like eBay or any other auction/BST site, you can get a few bad apples.
$99 at AT&T after $100 mail in rebate, NIB --- + 2 year contract.
And, I too would stay away from ebay blackberries---having been burnt in the past.
Good luck
