Geoff LitwackRichard - thanks for that link. I have an email out asking if I can use those images - what an amazing site he has.
David - interesting info. $20,000/each must drive the type collectors crazy. Is the other type significantly less expensive, or no? I almost hate to talk about money after the recent furor in the other thread, but it's not like either are within my budget anyway. 
I don't want to 'blow up the spot,' as the kids say, so I won't link to the auction, but any guesses what the P/F KBat on eBay is going to end at?
