On the recommendation of this thread I bought a sealed Ordyne and Buster Bros. from this guy. I received them today.
Very fast shipping.
Too bad the packaging was terrible! He tossed both of them into a small cardboard box -- one on top of the other -- with no additional packaging. Surprise, surprise, there was some pretty bad crushing on the Ordyne outer box, particularly from the Buster Bros. CD (which left a nice indent in the front of the Ordyne box).
He also charged me DOUBLE his shipping costs. Given that, you'd think he'd try a little harder to package them well.
Edit: On a whim I sent him a message asking for a partial refund of $5 which he accepted! He's ok with me!
