75lover..... try Ebay for the Motorworks subs. People post them alot. Here is a search result with just "motorworks" as my search.

You can try USS Dallas and USS Chicago and pull one up as well. They run a little more expensive online. If you have a Walmart Super Center ( the REALLY huge Walmarts) that is where they carry them. Again, go through that thread because someone was buying and selling them to guys in here who did not have access to a Super Wally. I also know of a guy who might be able to help you out...he's my brother and lives near a super wally. For a little compensation he could probably hook you up. Let me know!
