Just bought a NIB Halloween Beep on E-Bay, for $125. Description says it was made in 2015, and is an Aristo-RMT Beep. . Front of Box says Beep GP 7/9 Diesel Locomotive. (It was listed at $175 or Best Offer. I threw in the low offer and it was accepted.)
It will arrive by April 27th. I'll see how fast it runs, and take a picture of the circuit board, and post the info here.
Luckily, the Seller info says that anything can be returned if the Buyer is not 100% satisfied with it. So, I feel pretty safe about returning it if it runs slowly.
I have no use for the Halloween decorated shell, because I already have the Sante Fe shell I want. So, if I keep the Beep, I'll post the Halloween shell for sale in the For Sale section.
Thanks,
Mannyrock
