Conspiracy theories much?
Seriously, I think it's a combination of finding items boxed away during the move and a liquidation of motors that never quite took off (hence the no-support statement). As far as not buying a Neu motor, don't worry: IIRC, Neu gets royalties (or whatever it's called) on every motor sale.
I don't know if it was an unintended consequence, but this sale may just squash some sales for the CC knock-offs you see popping up.
The only thing I think Castle should have done differently is maybe give the dealers (like Mike) the $60-$70 deal and let the dealers in turn sell them for a small profit. They would most definitely have charged more (like $100 or so), but they would still have sold like hotcakes. And shops like RCM are geared for selling small quantities to consumers, so the shipping snafus would probably have been avoided altogether. Not to mention it supports the dealers. Just my $0.02...
