Yep, everyone sold out on the subway sets and ebay prices are through the roof. Hopefully they continue making them if not the prices just gonna keep going up.
I recently received the reflective tape which Strap Hanger suggested and upgraded by PS2 battery to BRC-2.
I have a PS1 R42 set, and thinking about upgrading it to PS3, but I don't wanna loose the Yankee Stadium announcement, so I'm still debating it.
