Lots of half truths and assumptions floating around here.
All the CF's sold, including 3 extras (after 75) that were assembled from spare parts. These a last 3 models were sold as DC only as the DCC systems were consumed in the 1st 75 models. I don't attend shows so maybe the 3 someone saw were Dave's personal models.
I bought a KEY CF and a KOH's Challenger and both are remarkable models. The KEY was every bit as nice in detail and came with some nice electronic upgrades that weren't available when the Challenger was built, plus it had other items modeled that had never been done on a production model. It remains to be seen how the KOH's BB will turn out.
I haven't ordered anything from KOH's since the Challenger, as his business model just doesn't suit me..........I will never tie up that amount of money again and hope for a delivery. Losing a $300 deposit (KEY) for any reason is one thing....the possibility of losing thousands, makes no sense to me. To me, it's not a matter of if, it's a matter of when. Someone will be left holding the proverbial bag IMHO. And now, hearing deposits being forfeited without the buyers knowledge, is just incredible.
The KEY factory burned down a few years ago, if you will remember, and considering Dave's age I have no idea if he will jump in again or not. I know the KEY BB project is on hold.
